This January we (4 colleagues) stayed for two weeks in Gisellas apartment when we were attending a workshop in Vienna. The apartment looks great, just like on the images. It is really huge (one could almost get lost) and offers enough space for both, privacy and social activities (separate bedrooms, three bathrooms, large kitchen and living room). The view from kitchen and living room is amazing (directly towards Augarten), we could see some fantastic sunrises over Augarten when having breakfast.
Gisella was very friendly and helpful!
We enjoyed the stay very much and can highly recommend Gisellas apartment to business travellers as well as to families staying in Vienna.
