Outstanding flat! Spacious and clean, and everything was as described. In addition to being centrally located with quick access to the tram or city center (walking), there is a fantastic dog park only two blocks away close to the river. We cannot recommend Petre and this flat highly enough. We will look to stay here again when back in Vienna. Also, there is a parking garage two blocks east on Gonzagasse where we parked our car. While it wasn't the cheapest (~25euros/night), it was close and accessible via ground level lot.
