We stayed at David's while looking for a flat in Vienna for two nights. Pretty busy times, but it didn't stand on the way of noticing his hospitality and how great of a host he is. The room is spacious and nice, and takes plenty of sunlight. TV with Netflix was helpful for relaxing after a day of walking around and talking to potential landlord/ladies. Very good stay overall and totally recommended. Oh and the best viennese restaurant in town happens to be just next door.
