The apartment was very nice and near to public transport. We couldn't meet Gisella because she was out of town but Alex, her friend, was waiting for us when we arrived and was very attentive. The only thing that we missed was a door between two of the rooms (we were 5 people) to get some more privacy. I would recommend her apartment if you're looking for a cozy house, close to the public transport to visit all the things from Vienna :)
