We stayed in Sandra's apartment for 10 days. Sandra was a wonderful host and made sure we were well looked after. We have two kids, so the back garden, complete with kids slide, sandpit and toys, was a real treat, and must be a rare gem in the middle of any city, yet alone Vienna. The apartment is clean, spacious and comfortable, and just up the road from the Museumquartier and all the rest of Vienna's great sights. There is a tram stop outside the door and the uBahn just a few minutes walk making getting anywhere straighforward and quick. We would definitely use the apartment again next time in Vienna. Thanks Sandra.
