Things are cheap which is really nice, feels safe, lots of clubs and nightlife is fun (they stay out really late). Castel isn't as cool as I thought, it looks pretty modern. The architecture is really cool though because it's so old. Prague is smaller than i thought, it's really easy to walk everywhere you don't need to take the metro. Not as many sights to see as other cities though. Less art museums than i would have likes personally.
