Max is an amazingly friendly host, he always responded very quickly. Apartment was shiny clean with big comfortable bed and additional amenities such as coffee. Near the apartment there is a bus directly connected to the airport, U-Bahn station and tram station, however as it is quite near the Innere Stadt, we preferred walking the distance rather than using the public transport (it is a beautiful walk I must add). In the neighborhood there are also many cafes and restaurants. I highly recommend staying at Max's apartment while visiting Vienna.
