It was all as described in offer, and you get what you pay for. Communication was good, place was clean, and it was generally pleasant stay. The only "problem" (if one can call it so) was the microwave/oven that didn't function properly. It is relatively close to Schönbrunn castle, and Mariahilfer Straße (famous shopping streat), and it is generally nice place.
Thanks Ursula for you hospitality!
