The residence is fantastic. It's very close to dozens of great attractions in Vienna, and there's also a lot of dining options in walking distance. The apartment is quiet; even though you are close to trams and a big street. The apartment is perfectly clean as well as fully equipped. It's spacious and well-lit, and the balcony is perfect for drinking a coffee in the morning.
Furthermore, the communication with the owners is super fast, and they are very helpful and forthcoming.
I had a more than pleasant experience staying here, and I can only recommend it to people who visit Vienna.
