Very spacious and clean flat in a quiet neighbourhood. Nice interior decoration. There's everything you need for a short stay. About 15 minutes walk from Wien Mitte. Rainer is very helpful and gave us very detailed instructions of how to get to this place. He also shared a lot of information of the city transportation and where to eat. We stayed for two days and went to two restaurants he recommended, both are really good and not expensive. Oh there's even a bottle of champagne in the fridge as a welcome drink !
