Christoph and Kaylee have a wonderful apartment. A colleague and I stayed here for 4 nights and it was way more than either of us expected. The bath and the kitchen were especially appreciated. A great place to stay in Vienna. Close to the subway station and easy to reach by Bus.
The communication with Kaylee is clear and quick.
The check in procedure is efficient, you’ll get a code to get into the apartment, so no messing around with keys.
