We loved the apartment! It is very stylish and sparkling clean! Charlotte was also extremely friendly, helpful and responsive. The apartment is very centrally located which we loved. It is only a 2-minute walk to the airport bus stop and only a short walk to downtown/key sights as well as to the Donau Kanal. The only downside was that since the weather was very warm during our stay we wanted to sleep with open windows, but then discovered that there was quite a bit of activity/noise on the street below the bedroom during the night. Vienna seemed to be alive with people enjoying the unusually warm weather that weekend!
