The apartament was big and clean, the rooms were nice and the beds comfortable. There is also a sauna which was great to get inside after a day of walking in the cold also a pool table for some late evening fun. The only problem I had was with the temperature. It was a little bit chilly especially at night, I asked Alex and Kate to turn the heat up and they said that they did but we didn't feel the difference. We went in February and it was a very cold week in Prague.
It's a great place to stay in Prague, I recommend it.
