I liked staying here and would again. 6 minute walk to the U4 station Meidling Hauptstraße.
The flat is modern yet simply decorated. Enough towels are provided. Even shower gels were provided. Hand soap was provided. The folding futon (couch) is actually quite comfortable to sit on. The TV worked fine. The mini fridge (NO freezer as far as I saw) worked fine and was clean. The shower pressure was good. The bed was actually really comfortable. There is so much closet space for guests to store their belongings. A couple of plastic hangers were provided as well.
I find it to be of good value, quite clean, and it was very quiet most of the time in the building.
As far as the electronic (code or app operated) lock system, I had trouble opening the door at first, but I recommend pulling the door handle back when you enter it, and then try to push it after you hear the electronic lock rotation.
Thanks so much for the accommodation!
