We had a great stay (3 adults and 3 children) at Ysabel's spacious, elegant and charming apartment which was better than advertised. We used the 3 huge bedrooms which were very comfortable, tidy and spread apart.
The apartment is located within walking distance from the city centre and a hop from Museumsquartier as well as next to Vienna's shopping street (Mariahilferstraße) and to the popular market (Naschmarkt) which offers now trendy bars and restaurants. The access to the U-Bahn is nearby which can take you quickly anywhere in Vienna. There is a supermarket nearby that is open on Sundays.
Overall, this has been a great stay and we intend to come back.
