Really nice place and very clean. If you are looking for a simple but cozy budget option in Vienna this is the place. The room is spacy, the bathroom is very clean and new. It is a bit far from the city center (a good 30 minutes walk) but you have a tram nearby. The check-in and checkout are great. A box for the key, passcode, everything is sent via WhatsApp or airbnb message.
Also, wifi works only very well near the bathroom and not in the living room.
