We had a wonderful time in Prague and fully enjoyed Katka's apartment.
The apartment is exactly how it was describe on the site (the photos are really recent): cosy, clean, at a walking distance to the city center where all the attractions are.
Katka was friendly and gave useful information upon our arrival and before. We had a late flight( in the evening) and she was kind to let us stay in the apartment later than the check-out hour.
I would definitely recommend the apartment and gladly return one day.
