I had a very good stay in Vienna thanks to Sabine. She is a nice host, welcomed me from the snowy journey with tea, we had good conversations (though I was not in the flat during the day) and she has a huge recommendation of (good for me as I am a vegetarian) veggi restaurants. The flat is located very central (walking distance to Rathaus, University, and the Museum District), it is a clean and friendly place, with shopping opportunities around. The room is a perfect size for 1 person, with a big shelve. I enjoyed the stay a lot and can recommend it.
