The apartment is located in a peaceful and well-connected neighbourhood (S train, bus, tram), near 2 supermarkets at 2-3 minutes walking time.
We visited Vienna in december and we had no problems with the heating of the apartment, it was warm at all times.
The apartment has all the kitchen appliances you need and the beds were comfortable and clean.
Alex is an amazing host, he was always helpful and we had a great stay!
