It was an excellent choice for a single traveler.
Communication went smoothly, the check-in instructions were clear and easy.
The apartment is as shown in the photos, clean, spacious, lots of natural light, in good condition and with a well equipped kitchen. There were tips and info available on local shops, restaurants, cafés etc., it was really useful and appreciated. Nice and warm in this winter period.
As mentioned by others, the location is convenient, close to U-bahn and tram stations, but also close on foot to the main train station and the city center (10-15 min). An excellent base for exploring beautiful Vienna !
