We stayed in the air bnb for 4 nights and enjoyed it. It's a studio located in the trendy Neubau neighbourhood with a lot of cool shops, hip coffeebars and nice Austrian diners (called 'beisl' in German) nearby. The studio is part of a building with a charming courtyard. The air bnb is perfect if you're looking for something that is well located and provides all the basics for a citytrip accomodation.
Two tiny remarks: the bathroom is rather small and outdated and the sleeping pillows offer little support. Something which can cause some discomfort for bad sleepers.
