We had a very good stay at the aparment on Große Schiffgasse. The apartment was clean and comfortable. It is quite small, but good enough for two people. I was there just over a week and enjoyed the stay. The location is excellent, it is a 15 minute walk to St. Stephens in the city centre, and less than 5 minutes to the Schottenring U-bahn station. The neighbourhood is very quiet as well. Only a 5 minute walk from Billa where you can pick up groceries. I would recommend this apartment for anyone staying in Vienna for a few days. If you are there on business it is a short u-bahn trip to the Vienna International Centre (15 minutes door-to-door). I would definately return next time I am in Vienna.
