My wife and I stayed here for 4 nights in early August and really enjoyed our stay. The young chap on reception was very welcoming on our arrival and was most apologetic that the internet was down. Not a problem for us, we didn't need it. Our apartment was on the top floor of the beautiful old building, and it took us 2 trips in the rather small lift from the 1st floor.
The apartment was very spacious and well equipped, the only fault we could find was the lack of air-con, it was very hot while we were there, and with the windows open there was a lot of late night noise.
The apartments are very well located, short stroll to main square or Charles bridge.
If we return to Prague we would certainly stay here again.More
