I stayed at Robin's apartment with 3 friends and we had a fantastic stay !
It is exactly as the pictures show with everything you could need (bathroom products, kitchen essentials and every amenity listed).
The apartment is very close to the subway and tram lines that gets you directly to the center and all the attractions. The neighbourhood is quiet and full of restaurants, cafés and small supermarkets easily reached by foot.
Robin is very easy to communicate with and gave us plenty of recommendations that were very useful.
I fully recommend this place and I would go back if I travelled to Vienna again !
