We really enjoyed our stay in Vienna! The apartment is equipped with everything you need, clean and comfortable. You will also find a short "read me" with all important information and also recommendations for restaurants and places to visit. WiFi works well :-) The location is quiet day and night, we could sleep very well. Communication with Osnat was always easy and friendly.
We would definitely recommend to arrive by train or bus, not by car as we did, because you really don't need it to get around and parking lots are quite expensive. Public transport is very good - from "Praterstern", which is ~8min walk from the apartment, you can get everywhere; bike sharing stations are nearly everywhere.
All in all, this apartment is a wonderful place to stay and a great base for exploring the city!
