Stayed at the place for over 3 months and couldn't have made a better decision. The apartment is really close to the city center (7-14 mins by tram) and close to many other attractions. Also, there is a tesco and several stores 1 minute away so you can have anything anytime. The apartment is really good and spacious. Josef helped me with any question I had and in all the time I spent there, I never had any problems with him or the apartment.
If you are planning to go to Prague for sure stay here, really really recommended. When I return will stay at this place again!
