We had a lovely long weekend stay at this apartment. The check-in/out and communication were quick and easy. Another guest had accidentally locked the common door, but after a quick call the door was opened. Sascha also immediately followed up with a phone call to double-check that everything was alright. Greatly appreciated! The apartment is lovely and really clean, and we enjoyed some downtime in the apartment as well. The location is good - not many restaurants around but only a quick U-bahn trip into the city center. We loved our stay here and will definitely book again on a next trip to Vienna.
