We had some trouble with check in because the key was not where it was supposed to be and instructions were given too late but overall it got resolved within half an hour.
Location is good, not the prettiest part of Vienna but good food around and easy access to public transport.
Place could use a deep cleaning, it's only clean if you do not look too closely in cabinets, on the floor or under beds.
We didn't bring a baby bed for our 1 year old because it was offered in Airbnb, couldn't use it though because it was extremely dirty and stank.
overall the place is spacious and good for a visit in Vienna.
