The apartment was exactly as described, Igor was a great host and extremely flexible. When we changed our arriving plans he accommodated immediately with an amicable response.
Not to forget that the apartment is quite fresh and new.
The apartment is 5 minutes walk to the subway station (U-Bahn) and very close to the Vienna Central station (where you arrive and go to the airport from).
The neighborhood had a good number of restaurants and grocery stores nearby. (We always ate at restaurants).
In conclusion, it was a pleasant and relaxed experience.
