The check in and check out functioned just perfect. The apartment has a perfect location, only few meters away from the Opera House or the Naschmarkt. There is an metro station around the corner if required. Its in an old representative building with elevator. The apartment itself is gorgeous. Its nice furnished, there is everything you need, incl Nespresso machine with some capsules included. The rooms are very spacious and in the reality they seem even bigger. There is a very good balance between price and quality. I definitely would recommend this apartment!
