The apartment is new, very clean and beautiful. Several supermarkets and markets are close by. U3 is a few minutes' walk away and in 10-15 minutes you are in the center, there is also a garage nearby, as well as the bus stop 10a in front of the entrance with which you can get to the Schönbrunn Palace or the ZOO park or you can walk for about 15 minutes. Easy check-in and check-out.
Sam was very quick and kind to answer to all questions.
Smart choice if you want to stay in Wien.
