We had a lovely stay at Christian's apartment. Everything was in good condition and the apartment was very clean. The pictures shown are really representative of the apartment. Christian's communication was clear and fast, there is also a map with information about the city (in English and German). The apartment is a little out of the city center, but easily accessible by two subway lines. A very good facility for staying multiple days, close to convenience stores. We went to concerts in the Vienna Stadthalle, which is only 20 minutes on foot. We higly recommend!
