We were hosted by Mary, who welcomed us very warmly!
The apartment was very nicely situated with the big Augarten park right next to the building. After closing your door it took roughly 20 minutes to be in the city.
The building itself was a very nice old Viennese building on the outside, but a very modern inside. We were happily surprised when we arrived, the place looked like a hotel! The keyword was "complimentary" - everything you can ask for was included.
I would highly recommend Kiki and Mary's place.
