This apartment is really big and beautiful and airy. The couches are very comfortable, and the bathroom is modern. I would stay here again any time, it was a great base for exploring Prague. I didn't cook, but the kitchen looked well equipped.
It's right in the center of a very busy part of town, so if you anticipate early bedtimes or you're a sensitive sleeper, you might want to bring ear plugs. I really only needed them one night, when it was hot and I was sleeping with the windows open.
