Unfortunately I can't write a good review. The main issue we had was that the apartment was dirty. The kitchen sink was filthy and the sofa bed is covered in stains. The throw over the double bed also has stains.
Other issues are: 1) some light switches hanging off the walls, 2) lack of crockery and cutlery in the kitchen, 3) only shower is over the bath with no fitting so you have to hold it in your hand, 4) water pressure too low to wash well. The whole place is tired and in need of revamp. Stefan is a good host but needs to work on the apartment for it to remain competitive in the Vienna market as there are other properties for much better value.
