My wife and I have just spent a lovely week in Ingela's apartment in Vienna.
The apartment was exactly as described and was perfect for our requirements. The location is excellent and all parts of Vienna are within walking distance (even if you are not as active as you once were!). Two local mini supermarkets are within a few minutes walk and they stock almost anything you would require on a short break holiday. Cafes and restaurants and within a few steps of the front door.
Neustiftgasse is a fairly busy and noisy street but once you walk through the outer doors to the apartment block the city seems miles away and the little patio garden is like an oasis of tranquility.
We really enjoyed Vienna and our stay at the apartment.
It is easy to see why Ingela has such a good reputation as she was superb answering questions at the booking stage and very attentive throughout our stay.
I would recommend this property without any hesitation.
