We had a marvelous Christmas week in a very nice Christiana's apartment!
The place is freshly renovated and equipped with everything what could be needed for regular life cycle (cooking, washing, etc.). Apartment windows look on the internal yard hence it is very quiet inside during the whole day.
Apartment itself is located very convenient for deep city exploration as city center area as historical neighborhoods and Shoenbrunn palace. For example, our longest trip for sightseeing took only 30 minutes door to door via public transportation with one change.
Thank's to Christiana for providing exhaustive recommendations on everything we asked for, including gastronomy shops, restaurants and their opening time during Christmas days, designer shops and other useful tips.!
In the end we liked our stay that much that didn't want to get back home at all!
