Peter was a very caring host with really good tips for visiting Prague. Even though we spent two nights there, we had a short but great experience. The maisonette flat was spacious and clean. In the summer it gets very hot but there where two cooling fans to cool down the place - its bearable.
Close to the flat, you can use the tram to get to the city center. Supermarkets and malls are close as well.
Riverside is in a 7 minute walking distance.
Recommending this place and host warmly!
PS: Keep in mind that there is no elevator to get to the 4th floor. But it is worth it :)
