We had a fantastic stay! Jo could not have done more. He even had food in the fridge for us! The apartment is large, spacious, clean. It is on a really nice street, near shops, bars and really good restaurants, but the apartment is still really quiet so you get a good nights sleep! it is very close to the metro (Ubahn), which is one of the best things when you want to explore Vienna. All in all, a brilliant host, apartment and location!
