Osnat was very welcoming, giving me a thorough tour of the apt and its amenities, and was very responsive from when I first booked through the end of our stay. The apartment was extremely cozy and peaceful - perfect for when we returned tired from a full day of walking. Both beds were very comfortable and we were able to get great sleep at night. The closest U stations are both under a 10-minute walk, which allows you to get acquainted with the local (i.e. not touristy) neighborhood, which includes good local food joints, little markets, small cafes, etc. Would definitely stay here again - have us a great place from which to experience Vienna.
