I stayed in Renaud's place for 6 days and it was a really good experience! I suggest everybody to stay at Renaud's place: the flat is very beautiful and very closed to the metro station (3 mininutes walking). The location is very closed to the city center (3 stops from the city center) and well connected by bus. Renaud was a very great host, he even came to pick me up at the airport, he help me with luggage and he gave me some tips and advises for travelling and living in Prague. The flat is very clean and there's everything you need!
