This is the best choice when visiting Vienna. I really like the discreet manner how this is hosted, everything worked perfectly when followed the instructions. Keys were available with pincoded safe and fluent is the word to describe how all works with this host. Apartment is close to main railway station, where comnection to airport takes 15 minutes. Its close to shopping street and there is grocery store in 100 meters. I like the most that you go in, you go out and you dont have to talk to anyone if you dont want to, everybody takes care of their own business. Everything is on place, clean, well equipped and apartment is so silent that you cant believe you are in downtown area.
