Josef and Celine are very friendly and helpful hosts. Communication was great and Josef and Celine were very helpful when we needed them during the stay. Their apartment is not only comfortable and well connected, but also quite special. My boyfriend and I enjoyed staying in this warm and fresh small place while we were visiting the city and our friends. The location is great! About 15 minutes walking from the city center and the Museum Quartier, really well connected with trams and metro! It is now top 1 of my list for a future visit to Vienna!
