Really nice experience! The apartment is located a short walking distance from Schönbrunn Palace, Billa supermarket, restaurants and metro station (U). Martin took care to also print all these attractions, even where you can enjoy the best applestrudel in Vienna :). We received details before we checked in about how to get at the apartment, the parking lot where we can leave the car for a longer period, etc. Communication with Martin went quite well and quickly. We had a small problem with the heating when we arrived but he came to us very quickly to give us all the details. Martin is friendly and you can spend hours with him telling stories, we really enjoyed getting to know him. I highly recommend staying at Martin's place.
