We had a late flight so I was worried check in may be a problem, however the instructions were detailed and accurate so we had no issues getting in to the apartment at all.
Once we got into the apartment straight away we could see how clean it was, and it smelled lovely which is always a nice touch. Amenities were great, shower was powerful and hot, it was cosy and warm at all times without us even having to adjust any settings (and as a person who is cold all the time this was a big plus!).
Nice modern apartment, in a good location for the underground to get around Vienna easily. It was quiet, no noise at all from surrounding apartments or outside.
Osnat has been quick to respond and very helpful since the point of booking, she is a great host. I would use her apartment again and recommend to others.
