It was a great experience with Petra - she hosted us well, she was very sensitive to our needs, and the breakfast was amazing! The location is good and close to public transportation and the main sights by walking in the lovely streets of Prague. The apartment was clean and quiet.
The only issue was that we expected to have AC in the room as mentioned in the reservation, but we had only fans. It was too warm for us in the place at the end of July.
Highly recommended :)
