My parents stayed at Katerina's place during their anniversary trip to Vienna. Bernd was waiting for them as they arrived via taxi and led them to the easily accessible apartment off a quiet street. Bernd gave them a thorough introduction to the apartment and neighborhood, including places to visit and eat. Throughout their stay, Bernd and Katerina made themselves available and were quick to answer any questions they had.
The apartment is very spacious and was wonderfully clean! All appliances worked well and the full kitchen allowed for the preparation of any meal if they chose to eat in. Despite being located on the first floor, it was very quiet and peaceful throughout the stay. The apartment is located in a quiet part of Vienna. The local food store, Billa, is a short walk away and has everything you'll need. There are several restaurants very close to the apartment. In addition to local cuisine, there were a number of smaller market-type food spots including a great burger place. There was also delicious (and affordable) pizza right around the corner.
The listing was very accurate in what is and is not provided - please do note that bathroom toiletries (i.e. shampoo, body wash, etc) were not provided during this stay, but otherwise everything they needed was available!
The apartment is close to all transit, buses, trams and metro which my parents used throughout their stay. It's an easy walk to the Old Town section.
My parents thoroughly enjoyed their stay and raved about Katerina and Bernd. They HIGHLY recommend any visitors looking for a nice stay in Vienna to book with Katerina and Bernd.
