We loved our stay in Wien using Isabella's apprtment. It was clean and tidy, the hosts left us handy notes which was really great. We really felt like home :). The flat itself is really close to the Belvedere palace, which have amazing gardens and some other museums. You can get to the closest tram in 5 minutes walk, from there you can access the main train/subway station of Wien within 5 minutes as well. Overall we had a great experience. Thanks Isabella for taking us in!
