We stayed at Christoph apartment for 5 nights. Christoph was very communicative and responsive to our needs. The apartment is very big and hosted the 4 of us very comfortably. There is an elevator in the building and the apartment it is very quiet. The heating systems was very effective , the bathroom had good water pressure and hot water with lots of towels (in different colors which is perfect for several users). There is several supermarkets nearby to shop from. The apartment is approx. 15 min walk to the center of the Vienna. There are lots of restaurant nearby. Thanks Christoph for your kind hospitality.
