We were three friends staying for the weekend. It's located in the 7th district close to main streets (such as Neubaugasse and Mariahilferstrasse) with many stores and great restaurants on every corner. The apartmant is huge and suits for at least 4 persons. We found there just everything we needed. The check is independt and was very easy thanks to the clear instructions we got from the owners Christiana, included photos of the entrance, the mailbox etc.
A Gerat recommendation in any aspect.
