Really nice and comfortable apartment, located near Yppenplatz with nice places to eat out. It's a bit out of the center but the public transport is just outside and the center is quickly reachable. That being said, you might hear some traffic noise but the apartment is in the top floor and well insulated and it wasn't a problem for us. If you are light sleeper, bring earplugs and you will be OK. What really stood out is the communication with Stefan. Stefan was reachable within minutes, offered suggestion and even offered that we come earlier because they managed to prepare the apartment earlier. We will definitely consider the apartment if we come back to Vienna.
