I was there in this apartment on end of Dec 2105.
It was good enough for 2 families. A neat and moderate apartment.
We parked our car in Hutteldorf P+R and got a metro to Langfeldgasse , from there we got bus no: 12A to the apartment.
Only problem that felt was the low signal strength of Wifi. Hope they could improve it.
Overall it was pleasant stay. Thanks Johannes
