Pros:
The location is very good, close to Mariahilferstrasse.
The host is very nice and helpful.
The apartment had everything it needed.
It's quiet and central.
Cons:
The toilet had a bad odour.
During our stay, the elevator malfunctioned and we were forced to use the stairs daily. It wasn't that pleasant because the apartment is on the 5th floor.
It's a bit small for a family of 3-4 people.
