This Airbnb was adequate. The location was walking distance to many tourist locations in Vienna and the place is clean.
I do have some complaints: the bed was not comfortable, the mattress was the same type of lumpy material as a college dorm futon. The slats on the bed had come unstapled, so several times a night we would crash unceremoniously to the ground, and have to get up and reposition the slats. Most of the rooms were very dimly lit. Overall the place was tidy but the bathroom had a lingering odor that no amount of sprays could hide.
