We had a great time in Gisella´s apartment. It is very well located. Sufficiently near the Ring so that good walkers can reach it in around 20 minutes and at the same time in a quiet and pleasant neighborhood. It has varied and excellent public transportation available in a 150 meter radius. The Augarten Park is just in front of it. One can enjoy it at evenings from a balcony, especially since at this time there is very little traffic on the street. The Augarten is very usable for families with children or simply for anyone who wants to have a pleasant walk.
The apartment itself is ample, comfortable clean and well equipped. We stayed there as a family with 4 children and often had dinner at home.
Gisella (and in her absence her colleague Alex) were excellent hosts, immediately available (either by mobile communication or personally) and always supplying prompt answers to all our requests.
We highly recommend Gisella and the apartment at Augarten.
