Location, location, location! This Airbnb is right in the centre making it easy to walk to many sights and for further away you have easy access to the U bahn at Stephansplatz. As for the room itself, it is cosy and clean. The door opens straight into the communal living area. It is not sound proof so you will hear the TV, telephone calls, etc. if you are in your room. You are sharing bathroom and kitchen with one other person which worked out fine with me (some reviews give the impression that there are a multitude of people staying here). The room is not lockable but you need have no worries about the safety of your things. You have your own key to the apartment so you can come and go as you please. I never got back late but the host told me other guests spend the night out and is tolerant of them getting back late. If you choose this Airbnb I am sure you will enjoy your stay.
