Sebastian and the girl that welcomed us were very kind and helpful. After assisting us in finding the best parking possible for our stay in Vienna, they treated us to a welcome drink on our terrace. Whenever we had any questions, they were answered immediately and they were ready to help at any time. The apartment had anything we needed for our stay, and especially the coffee from the espresso machine was very good. The location of the appartement is excellent. The day of our departure, they allowed us to store our luggage for a few hours as to not pay for extra parking. Overall a very good experience and very chill hosts. Greatly recommend!
