It was really a very good experience. The apartment is perfect and the neighborhood is very safe and charming. There are good restaurants not far from it.
We were very well welcomed by the mother in law of Georg who made her best to explain to us what to see in Wien.
The communication with Georg is very easy and he answered very quickly to all our questions. He didn't hesitate to come in order to solve a problem with the washing machine, despite the fact that occurred on a saturday evening !
We definitely recommend this apartment.
