Our stay in Vienna was great. The City is fantastic and I thoroughly recommend that you you visit Vienna. Roman's apartment was clean, tidy and well located. You are a few minutes walk from he Haydn museum and also the main shopping street (Mariahilfer Strasse). There are also plenty of good eateries nearby so you do not need to venture far in the evening, if like us, you have done a lot of walking around the lovely Viennese sights during the day. My wife was particularly pleased that the apartment was warm and cosy as the outside temperature during our stay never reached more than about zero. Roman/Maria were great hosts, even though I did not meet either in person, their communications were prompt and very helpful. We were even able to have a later checkout owing to our evening flight times. I would definitely recommend this apartment for anyone wanting to visit Vienna.
