We thoroughly enjoyed our stay in Johannes and Johanna's appartment. It is spacious, comfortable, warm and clean, and its location is ideal for access to the old part of the city. There is a supermarket very nearby if you are self-catering, but also plenty of restaurants within very easy walking distance. Arranging to meet Johanna at the appartment to receive the key was very straightforward and she helpfully allowed us to leave our luggage there on the last morning before we left for the airport. All in all we were delighted with the appartment and being able to stay there added to our enjoyment of our short break in Vienna.
