Helene and Rainer met us at the apartment and gave us a warm welcome along with plenty of information about Vienna. The apartment was very close to U-Bahn stop Niederhofstrasse and we used it every day. The system of subways and trains is very easy to use and the waiting times are no longer than a few minutes. It is a quick trip into the city centre from the apartment. The apartment provided everything we needed including a kitchen with oven, drying room for washing and free wifi. Within a couple of blocks is a supermarket, cafes, chemist and other shops.
