We've visited Vienna for a week and decided to stay at Annemarie and Mottie's apartment. Great location, everything is accessible, the apartment is nice, warm and clean :)
Wi-fi is enough for surfing (even with video), but, for some reason, VPN didn't work well on it. Wasn't a big deal, but something to keep in mind if you are going to work in the apartment
I would say that I will definitely stay there again, given the chance :)
