We were unfortunate be there with road works under our windows and front door, and the building undergoing renovations at the same time. The redevelopments resulted in the aircon having to be turned off which was not fun in a hot Vienna. Our host was most apologetic, offered a discount and had provided a pedestal fan which made a bit of a difference, especially at night. That aside, the apartment was very clean and very convenient, in a quiet residential area opposite St Elisabeth Church. Easy 20 min walk to the city centre, 15 mins to the station and the lovely Belvedere Palace was just at the end of our street. A few small restaurants nearby, a little street market over the road and we liked the area. Would be happy to go back at another time.
