I stayed here with my friend and we had a wonderful time. Eva is easy to communicate with and responds to your message the same day, if not the next. The place was neat and clean when we arrived.
The location is great! It is right near the old town square, so it is very centrally located in the historical part of the Old Town but because you're staying on the 2nd/3rd floor and the window faces the inner courtyard of the building, you won't be bothered by the outside noise of the streets.
If you are looking for a cozy stay for 2 people in the center of Prague then this one is definitely recommended!
