Me and a friend had a fantastic week in Prague based at Umur's flat. The flat is easily accessible via the main shopping high street of prafue, which leads up to the Museum. Umur was waiting for us at the flat, and was always easily reachable via phone. He gave us a tour of the place and was extremely kind and friendly. His recommendation list also helped us find many things to do during our stay.
We didn't use public transport once (besides travelling from the airport) as everything is walkable from the location of the apartment. There are multiple shops nearby, and the main attractions are generally all within 10/15 minutes walk; anywhere you walk in Prague is interesting and picturesque so it's never a problem.
The apartment itself was extremely clean, warm, and well furnished. It is a few floors up from street level, so the sound of trams and hustle of the street is fairly quiet and you can have a lovely rest after busy days exploring the amazing city of Prague. Thanks, Umur!
