Alexander and Bettina’s apartment is a lovely space. It is very elegantly decorated and furnished, and spotlessly clean. It is also in a good location for exploring the city - within walking distance of the inner stadt and near trams and the underground. It is also nice and quiet.
Alexander and Bettina were very efficient and charming in handling all of our arrangements. We were very comfortable and had a lovely time in Vienna.
I wouldn’t hesitate to recommend staying with them.
