Diana is very responsive when I was making the arrangements . When we arrive, we received from her bottles of good wine as a welcome gift. Diana also written down many useful information to help us getting around and finding things to do and restaurants to eat. She is an excellent host. The apartment is beautiful, very spacious, airy, sunny, quiet, calming, and meticulously maintained. The location is quite central, yet quiet and safe at night. It was a short walk through a nice street with beautiful buildings to the closet subway. Or you can walk at ease to the central part of town with museums, theatre, and palaces. I will definitely stay there again next time I visit Vienna.
