Petra's apartment was perfect. It is only 20 minutes from the center and the train is next to the flat. The room is bigger than on photos and the terrace is amazing! We had bad luck because at those days there was not hot water in whole area but Petra was very understanding and she gave a discount for this (big thanks for this Petra!). In the apartment there was everything what we needed - and even more! Petra was the best host I've ever had, I could contact her anytime and she was very helpful. Even before our arriving she did her best to check in and check us out as we wanted. Also Petra's friend was great, she helped us a lot. If you are looking for nice place to stay in Prague, just chose Petra's apartment and it makes your trip even better!
