Convenient location about 5-7in walk from Wien Mitte train station, and near lots of amenities. Walking distance to St Stephen's Platz.
Budget hostel-type accommodations with shared small shower/toilet (one unit only for women, two for men), and a small towel provided. Room had fridge but no AC, and ventilation was an issue when I stayed there. I had no issues with cleanliness in room. common kitchen but I didn't use it. no common room.
Tony was very responsive and helpful. I'd suggest this place if you have overnight layover but maybe not for extended stay.
