Prague (or Praha) was one of the least bombed cities in WW2, so much of the old architecture is still standing. Czech food is great and the beer...well if you like beer this is the best place in the world to be.

On the negative side tourism has just gone through the roof over the last 5 years. So much that if I were going for tourism purposes I would go during the winter to avoid the crowds. I like to rent a car and drive out to the hinterlands to see old Czech.
