Great bnb experiment! Robin and Marc are very nice hosts! We could talk a lot with Robin, who is very friendly, social and available for our questions ! The flat is amazing : spacious with a mix of modern and old , and absolutly perfect for the cleanliness! Moreover, it is only at a 5min walk of one of the most central lines of Vienna subway. As far as the bedroom is concerned, it is very calm, and the couch bed is very confortable : you really feel well and can sleep as in a normal bed! To sum up : awesome and absolutly recommanded !
