There's a lot to see, but be prepared to queue, and always be prepared to pay. On my second day there, the Florence innkeeper summed it up by saying "in Italy, you pay for everything." Every attraction also has security checks, so travel light so you don't have to keep unloading stuff.
And when you take public transport, validate your ticket at the machines. Because if you don't, you get fined and you don't want to get fined in Italy. You will go bankrupt. I got fined but the young female ticket attendant took pity on us and let us off with a 5 euro fine instead of 50. She was really nice about it, unlike the other old male train attendants. Which was a good thing because if she had fined us 50, I'd have had to go home right there.
I also couldn't help but notice that Italian girls are hot. They are easily one of Italy's main highlights for young male tourists (aka me). They are always perfectly groomed, have good figures, and they know how to wear their clothes. And somehow, everyone in Italy loves wearing shades. It's an Italian thing.
If you ever get the chance, go to Italy. It is an experience you will never forget. Okay, time for pictures. Warning: Super long post.
Pisa
The only thing to see in Pisa. The Piazza Dei Miracoli, home to the leaning tower of Pisa.
Lol. Don't you love the leaning tower. The whole place had this happy mood that I couldn't find elsewhere in Italy. It was like some picnic festival. And italian gelato is awesome. I tried pistachio and straciatella (italian chocolate chip) here.
Try this cycle thing if you go to Pisa. It's 5 euros for half an hour, and you'll learn what it's like to be a trishaw driver. Invaluable internship experience.
I climbed to the top of the tower. It cost 15 euros but the view is worth it. The climb though will make you queasy, because after all you're climbing a leaning tower.Florence
If you're going to Florence, one good way to travel around is on a bike like this one, because the roads are flat, there is a lot of ground to cover, and public transport is rubbish. But rent it for a full day though (18 euros), because you will need a full day (at least) to cover all 4 of the main attractions in Florence.
If you're planning to cycle in Florence, make sure you're good with a bike. I can't count the number of times I nearly got roadkilled by ambulances, horse carriages, delivery trucks, other cyclists, cars, taxis, pedestrians, tour groups, and Segways. Of all things, Segways in Italy. As you can see the paths are permanently clogged, and the roads in Italy are chaos. It doesn't help that the drivers of vehicles generally don't look in front of them before they step on the accelerator pedal. I guess it's all part of the experience.
The 4 main attractions in Florence. The Medici Chapel, the Duomo, the Uffizi Gallery and Il David, displayed in that order. You have to queue for about 2-3 hours for each, and they all cost about 6 euros. Photography is not allowed in all of them, so you'll have nothing to remember your time there by. In my opinion, they all aren't worth the wait or the price, but it really depends on how big a fan of Renaissance art you are. If you aren't a fan, please don't go to Florence.Why do I have a photo of David? Well, they can't catch everybody.
Sometimes, the best views in a city are found where you don't have to pay money for them.Rome (Colosseo e Palatino)
I wanted to be a soldier but the old guy on the left crowned me and called me Caesar. Oh well, who am I to refuse. He gave me a sword as a consolation though.
I know, the Colosseo is damn awesome. It really takes your breath away when you see it.
Hurhur. Ice cream at the Colosseo. This time, its chocolate and strawberry.
I walked around in the grounds of the Palatino, next to the Colosseo. The Palatino used to be where the Roman imperial palace was, and it was the first structure of its kind to define the concept of a palace, so it is where the word "palace" got its name from. It is all ruins and gardens now, but still quite a sight.
The rest of the main sights in Rome, not counting the Vatican. The Monument a Vittorio Emanuelle II, Fontana di Trevi (Trevi fountain), Piazza di Spagna (Spanish steps), Piazza del Popolo, the Pantheon and the Piazza Navona. Of all these, the Trevi fountain deserves special mention. If you stand with your back facing it, and toss a coin over your shoulder into the fountain, legend has it you'll eventually return to Rome. And, don't drink the water. I tried it and it tasted bitter and metallic. Well, I wonder why.
Dinner with our roommates in our hostel, Alex and Brad, from America but currently on exchange in Copenhagen. We bonded really well because they were rabid soccer fans and we were totally in agreement that our hostel sucked. Haha.Rome (Vatican City)
St. Peter's Basilica. The centerpiece of Vatican City.
The inside of the Basilica. There was actually too much stuff inside here, like mosaic portraits, sculptures, smaller chapels, confession boxes, and even a small museum. After awhile I got overwhelmed with taking pictures and just gave up.
Can you believe the guards of Vatican City have to wear this uniform. If it wasn't for the poleaxe I'd have thought he was the court jester.
The Vatican Museum. The Sistine Chapel is inside and it's worth the visit, but the price is a bit steep (14 euros). Photography is not allowed inside either, so it's just one of those things you see and forget.
Vatican ice cream shot! This time its hazelnut and lemon.
Castle of Saint Angelo (Castel S.Angelo) near the Vatican. I think it would have given a nice view of Rome from the top but I didn't go in because it was 8 euros.
Ponte (bridge) Vittorio Emanuelle II. One of the many nice bridges that span the River Tevere in Rome.
At the Colosseo at night for the Stations of the Cross. The Pope conducts this session on Good Friday. I was just there to see the man in action but I guess it's an occasion of huge siginificance for Catholics worldwide. In case you're wondering, the old man carrying the cross in the last picture is the Pope.Tivoli - Villa D'Este (ouskirts of Rome)
If you are visiting Rome and you have some spare time, you must go to the Villa D'Este, on the northern outskirts of Rome. While I wouldn't go so far as to say it beats visiting Rome, it came damn close.
The villa. Pretty nondescript. But that's till you see the gardens.
The view of the surrounding area from the villa.
The garden was super gorgeous and fun. It had like 200 fountains. Total madness.
Ice cream in Tivoli. I decided to try something weird and went with melon and puffo. Puffo apparently means "smurf" or something, which explains the bright blue colour. It tastes like paddle pop. People who are three apples tall should try this.
Talking with the guys in my hostel room. I think that's like where half the fun of such backpacking trips are. You get to interact with like random people from all over. The German guy was freaking hilarious, like damn full of shit. He's the one in the corner looking at the camera.
A group shot at Roma Termini before we parted ways. Apart from us two Singaporeans, there was one Colombian, one German, and two Canadian brothers.Venice
The gondolas are like freaking expensive. I heard one of the guys quoting like 80 euros for an hour. Alternatively, you could take a water bus for 6.50 euros. Come to Venice when you have money, otherwise, you'll be pretty bored, because it isn't very fun to walk really. The whole place is a maze, and there's only like two main attractions.
The Ponte di Rialto, the most important bridge in Venice, which leads to just about the only thing there is to see in Venice if you don't have much money.
Which is this, San Marco's Basilica. The last picture is a view of the plaza below from the top. You have to pay 4 euros to get up there though. 
They sell really huge and really good pizzas in Italy. Like seriously, Pizza Hut no fight. You haven't eaten pizza till you've eaten the Italian variety. And of course, the gelato shot. Haha. This time its coffee and cherry yoghurt.
It was really hot out in Venice. It was the first time since I'd been here that I've experienced temperatures of 20 and above.
And this is what angmohs do when there is sun.
You gotta love Italy. Despite how expensive it is, I have to say the place definitely has character.
