Trip was late November, so keep in mind this is a winter rating. Place is great overall in terms of hospitality, decor, amenities and so on. My missing star is mainly a criticism of the way AirBnB's have become; these are concept studio apartments, with numbers on the doors, a dead feeling, and no character. Not exactly what AirBnb's used to be. Perhaps people live here, perhaps they don't... you are getting what you see and the hosts are very nice and very hospitable, but -- specifically in the case of Vienna in the winter -- for the same price you may as well get a good hotel nowadays in a good locaiton and you're not missing much.
