Nice apartment on outskirts of Vienna in an old building. Lift/elevator operated by room key. Road outside is not noisy (during mostly holiday period). City itself isn’t really walkable but Uber proved both reliable and cheap.
Good, clean bathroom, separate toilet and kitchen with decent facilities.
One bedroom has 3 single beds. Be aware the other double bed is set within the main lounge/dining area which gives access (via kitchen) to toilet and bathroom, so no assured privacy or going to bed before others want to etc.
