This is a great apartment, at a very convenient location. The place is quiet, at the same time food stores, little cafes, public transportation are all "around the corner". Interesting museums are nearby and the Hofburg is also just an easy walk away. Hannah is really approachable, and she was very helpful and flexible about an early check-in.
We had a 7-year old in the party. He truly enjoyed riding around in the apartment on the toy car provided for children by the hosts.
