The apartment is a very beautiful and stylishly furnished historic building in a prime location.
Many attractions are within walking distance, as well as stores for everyday needs, restaurants, pharmacies, etc..
Also subway and streetcar are very quickly reached and thus you are also quickly at other attractions such as Schönbrunn Palace.
The apartment itself is very well equipped and has almost everything your heart desires (we only missed a toaster ;) ), check-in and check-out went smoothly and Kaylee is a wonderful host.
Highly recommended for any Vienna visit!
