My stay at Bernadette's place was very good. She's a nice host and I would recommend her to anyone who wants a pleasant and calm stay in Vienna. The dorm was big and clean, and the place is very quiet. It's also close to the city center (10 - 15 mins walk) and to the metro station too. I needed to check in a little bit earlier, and she agreed with no problems so it was very comfortable to me.
Danke schön Bernadette, und auf Wiedersehen!
