Carolyn's apartment was great. Located centrally is only a short walk in the city centre. We dealt with Paul before the arrival was kind enough to arrange a car from the airport and provide us with information about the local area.
The apartment itself is tastefully decorated as you see in the photos. There is a fair amount of construction work going on we we stayed which was a little noisy at times but it we were out most of the time so it didn't bother us to much.
I would definitely recommend Carolyn's apartment to anyone staying in Vienna
