The apartment is well placed, close to the metro station "Karlplatz". The hosts are very available and give excellent advice on the practical, touristic and cultural life of Vienna.
The interior is very nice, spacious and tastefully decorated. A pure mind as you see in the photos.
The portable wifi available is a real plus! The good surprise for me in the apartment. It allows you to have internet in the apartment, and when you go out you can put it in your bag and have internet everywhere.
I recommend 100% this accommodation. Thank your Eva and Michi :) !
