We had a great stay at Petr and Marcela's place. Public transport is very good in Prague and there's a tram station just nearby. So visiting this beautiful city was really easy and with Marcela's tips even easier.
I did not meet Petr or Marcela but her printed tips made things even easier. They were very quick in responding and that was really nice as well. Thank you very much!
The room is part of a shared appartment but we did not have any issues due to that. It was hot and humid in Prague when we visited. There is no ventilation in the room and windows cannot be opened so it can get quite stuffy in spite of the fan.
