The apartment is a great base for anyone wanting to visit Vienna as it is only 5 mins walk from the U1 underground with only around 4 stops to get to the Centre. For example door to door to the Opera House is normally around 17 minutes! There is a large supermarket right across the road. It is very quiet and all 3 bedrooms were large and comfortable. It's double glazed with excellent heating and a great shower. Yvonne was very helpful answering questions when we had any very quickly. We would definitely stay again.
