Very nice apartment. When you are for let's say longer than 3 or 4 days I would say it is 2 persons apartment. In our case just two days was really OK with 3 people.
The neighbourhood is very quit. Schönbrunn is nearby. Public transportation also.
In our case not everything was quite clean. We made a remark towards Christina on that, I'm sure she will pick this up.
Checking in was very nice. The housekeeper was very helpful, despite the fact that we were late due to enormous traffic jam on our trip to Vienna.
