Diana's apartment was lovely! It was spacious, clean, and well-located. I had one day in Vienna so I didn't spend too much time in the apartment but it was perfect for what I needed. I was able to get to most of the attractions easily by foot or public transportation. There were lots of cute restaurants and cafes within short walking distance. Diana was very responsive and was kind enough to let me store my bags in the apartment before the check-in time. All in all, it was a very short but great stay, and I would stay there again!
