The apartment was a good place to relax after a busy day sightseeing.
Very nice, clean and modern place.
Supermarket & metro station are close by - the metro gets you to a lot of places in the city quite quick.
You don't hear a lot of noise from the outside (or neighbors).
Christian is easily reachable and can answer a lot of questions.
As a couple we had a lovely stay and if we'd return to Vienna this is definitely a place where we'd go back to!
