Communication of Gerrit and a his co-host Sandra with us was perfect. We exchanged messages and their instructions as to the check-in were absulutely useful and correct. We were travelling to Vienna by car and I was bit afraid about the parking. But the details Gerrit told us were 100% correct, and it is really easy to find a place in the parking area some 300 mts. The parking is public but for the car safety there is video surveillance. The apartment is spacious and it was the same as it is on the picture. Floor heating was perfect. There is a TV in each bedroom and in the living area - access to Netflix. Sofa in the living area was large, perfect, comfortable as were the beds. It was totally quiet in the night but also during the day. Kitchen is equipped with plenty of stuff. Underground station is Vorgartnestrase is really some 300 mts. It is U1 line of metro taking you directly to the center of the city. Overall it was really good.
