Great location to visit Prague. Everything is within walking distance and shops are open even sunday. The flat is on the 3rd floor (no elevator), the house is old but the flat is newly renovated- looked exactly like on the pictures. It is small, very clean and nicely furbished. The windows open to a green inner courtyard. Everything you need is there and Tereza was a very thoughtful host.
Personal tip for breakfast nearby: Cacao V Celnici 1031/4, 110 00 Nové Město- next to the Billa supermarket.
