Jenny's place is well located, just a couple minutes walk from the subway station that takes you to the center in just 4 stops. The neighboorhood is quiet, perfect for resting and there is a supermarket just across the street. There are also several places to eat at much more reasonable prices than the overpriced centre of Vienna. The apartment was clean and tidy and had everything we needed for our stay.
Communication with Jenny was fluid and perfect and the flexible check-in was great since our flight arrived late in the night.
I totally recommend Jenny as a host and her apartment as a place to stay in Vienna.
