Sonja's place was a great apartment, very well equipped, very close to the Schonbrunn Palace and to the transport stations to the center. Also the aparment is located very close to two supermarkets, wich we find it very useful. Sonja was very easy to comunicate with, also she gave us some useful tips about how to get to the apartment. The check in/ check out procedures are very easy realizated through lock box. I consider Sonja's apartment to be very pleasand and cozy and I totally recommand it!
