I've been fortunate enough to travel to Prague two times, and I can confidently say that it is one of my favorite international cities. It's got incredibly beautiful architecture, loads of nearby destinations to check out, and of course, cheep beer (pivo)! Here are some of my favorite things to do in the city:
The first time I visited Prague I and my friends stayed at the Mad House Hostel right in the heart of the city. In all my years of travelling, this is arguably the best hostel I have ever stayed at! The hostel has a great location and was a great place to meet other travelers. Every night the employees would lead various social activities and show you all around the city of Prague. I highly recommend this hostel! http://www.themadhouseprague.com/
Overall, Prague is a very walk able city. That being said, there are also tons of transit options, including an underground subway and above ground trams that take you all over the city. Definitely spend some time meandering through the curvy streets and getting lost among the many shops and restaurants.
