Stefan is a great host and his place is quite fantastic. I communicated with Stefan couple of months before arriving in Vienna with my wife and 6 months old son. Initially we were a bit unsure about the place since there was no air conditioning. Through our communication, Stefan graciously installed an air conditioning system just to accommodate us. We had so much fun staying in his place. Apartment is in a perfect location near downtown area and walking distance to all the attractions. The street in front of the apartment is also full of shops and restaurants. There are at least two big supermarkets in 5 min walking distance from the apartment perfect for food and grocery shopping. Overall we had a fantastic time in Vienna thanks to Stefan and his hospitality.
