Reflection of buildings in the river by Ponte Vecchio.
Park Guell is once of the coolest places I’ve been to. It was designed by the same guy who did La Sagrada Familia (Gaudi) and offers an awesome view of the city of Barcelona.
Pro tip: I don’t know this first hand, but I’ve heard it’s a great place to trip acid.
The Coliseum is awesome. An obvious must-see when you’re in Rome. I’d suggest getting the headsets so that you know what everything in the Coliseum is. (I also think that you get to cut the regular ticket line if you are renting a headset.)
Venice is really beautiful, but not a place I’d spend much time at (especially if you’re young / looking to party and eat well). It’s definitely worth visiting because it is so unique, but I liked Florence and Rome far more than I liked Venice.

La Sagrada Familia- the most incredible architectural structure I’ve ever seen. Make sure you get the headset beforehand so you understand everything while walking around. I also recommend taking the elevator ride up for an amazing view of the city.
My favorite building in Rome (and possibly anywhere)- the Vittoriano. I love this shot because it was taken in motion and sort of gives the impression of time passing through the people movements.
