Maria's place is a great place: Spacious (bigger than expected), clean, tastefully decorated and very quiet (what I do appreciate). Check-in and check-out w/o any problems. Maria responded very fast. The place is not far away from Mariahilferstraße, you can even walk to the Kunsthistorisches Museum in about 8-10 minutes. Public transport (=underground) is also about 4-5 Minutes away. Tram is located in the same street of the apartment. I enjoyed myself very much and can only recommend Maria and her place
