For me, the best location in Viena! Near the very lively Nash Markt, the two most beautiful Otto Wagner's buildings, the best pedestrian shopping street in town (Marie Hilfe strasse) and two steps away from the underground and station on Wien bike. Theaters, bars, cinemas of the most genuine Vienna!
Otto and Teo are two charming and brave spanish-austrian students, polyglot, friendly and very helpful who made me feel at home from the first moment. The flat is elegant, warm and with a pleasant, tasteful and lively decoration which reflect the international life of its owners.
I would highly recommend this accomodation to anyone wanting to enjoy Vienna from its best side!
