We stayed in Petra's flat for 4 days. The apartment itself small but very cute, everything is like in the pictures. For us there were no problems at all, neither the bath tub in the kitchen, nor the toilet in the corridor. The greatest feature of this flat is the location in the historical heart of Prague. It's super convenient. 2 minutes to Old Town Square and 5 to the metro station.
Petra is a great host. We needed to stay for one night more and she agreed to give us this opportunity without any questions. I strongly recommend her and her flat for staying in Prague!
