The apartment was entirely adequate for our 4 days in Vienna. It is also suitable for a longer stay as it has everything you need, e.g. washing-machine, dryer, kitchen, etc. Location is good: in a cul-de-sac, so it is quiet; 15 minutes' walk to the edge of the inner city, or the U-Bahn a few minutes' walk; with a busy neighbourhood just a few steps away. Check-in with lockbox went smoothly. Communication with host was easy. The apartment was clean, but the building is quite old and well-worn, with quite a small (but modern) lift. The apartment itself has been renovated, but seems to have been rushed in places, so don't expect the paintwork and other decoration to be perfect. Overall a comfortable and pleasant place to stay.
