Our family of 7 stayed here for 4 nights. It was spacious. Having 3 bathrooms was a great feature. The location was perfect; a brief walk to the Charles Bridge, Prague Castle and the main square.
The staff went out of their way to help us. The receptionist even came to the apartment to show us around and explain features. Daily housekeeping service was a plus. They were able to arrange transportation to a bus station and the airport.
If you go to Prague, first go to Prague City Apartments!
