Petras place is the best to stay in Prag. It is really close to everything you need to see there and she gave us good advice where to go. Petra is a very welcoming host, she even fetched us from the station at 6:30 in the morning and made our stay as comfortable as one could imagine! The place is very clean and Petra made the best breakfast for us. If I ever visit Prag again I would definitly stay at this place again.
