My wife and I spent the better part of a week in the Widlers' studio. This is a very nice and clean apartment with comfortable beds and everything you need for a short Vienna visit. Not mention it is very close to the city center and a few minutes walk from the U-Bahn. The host met with us on the dot, even though we changed the meeting time only a few hours prior, and even paid for half an hour parking while giving us the tour and checking us in. A cheap Park and Ride garage is only a couple of km away and easily accessible via underground. Very satisfied with the experience, thank you.
