We spent four days in Prague and the apartment was perfectly located to get to all major points of interest walking or using public transport. The house was very nice and cozy, exactly how it looks in the images. Just a little dusty with some traces of the previous guests, I guess. Not a big deal anyway and we cleaned in a few minutes.
The apartment is at the third floor but there is an elevator. Kristina and her husband were willing to help and the last day they gave us the opportunity to stay in the house until the evening since there was no one else checking-in.
The neighborhood is nice and calm, with several restaurants/pubs and it's near the river. Walking on the riverfront at night is a real treat.
So the stay was basically great and Kristina's apartment is perfect if you are planning a visit to this European jewel.
