The apartment was just as pictured, clean and had all of the amenities one could ask for. Vivianne had even set up a small spa basket with everything you could need for a relaxing bath.
The location of the apartment was also great and albeit we walked everywhere (about 30 minutes to the city center'ish area) the tram stop was close by so public transport would also be easily accessible.
In regards to Vivianne herself, I have nothing but good words for the host as she was very responsive and accommodating. We had a great experience in Vienna thanks to her and the apartment.
