Clean and spacious. The apartment is in a nice neighborhood just a few minutes walk to the historic ring. The building has a lift. I arrived a bit early and had no problem storing my luggage before check in. Very friendly and responsive hosts provided clear instructions and good local restaurant recommendations prior to arrival. Once guests are checked in they are not allowed to go into the apartment to fix stuff so it would be wise to check everything at check in. In my case everything works great except WiFi. Was not much of problem since I had my own network. Overall I really enjoyed my stay and would come back if I’m back in Vienna again.
