Annemarie and Motti were very kind hosts. They gave us a lot of advices before our arrival, which helped us a lot.
Their appartment is very well located and you can reach easily the subway and all the interesting places in the old town by foot (and we did). The appartment was comfortable and clean with all the necessary. We had a great time in Wien and Annemarie and Motti were very responsive. I recommend you choose them as hosts if you come to visit Wien.
