The apartment is modern, beautifully furnished and luminous but we had a rocky start to our stay: there were minor delays in communicating with the assistant host and the apartment hadn't been cleaned after the previous guests, dirty bed linen and towels were still in place etc. Apparently this was due to some misunderstanding between the assistant host and the cleaning lady.
Nevertheless, after the initial difficulties (and when the apartment had been cleaned the next morning) we enjoyed staying at this beautiful apartment! It's close to an U-bahn station and a walking distance away from the Schönbrunn castle. Despite our difficulties we would definitely recommend staying in this flat as I'm sure the mix-up was just a rare accident.
