I stayed for four nights with my wife and a six-year-old son. My family had a very pleasant and comfortable stay. Rooms, bathroom, kitchen, and toilet were clean and maintained well. Towels and bed sheets were also clean and I was able to know they were washed.
Communication was quick and nice. Miriam and Philipp responded promptly and always tried to act from the perspective of guests.
Location was great. Access to public transportation, nice restaurants and cafes was easy. There were also two supermarkets (SPAR) in the neighborhood so I bought food and drinks easily at reasonable prices.
This is a great place to stay in Vienna where hotels inside Ring are too high-priced. I will stay here again definitely if I visit Vienna.
