Mickey was a great host for our short trip to Vienna. We stayed 2 nights for a concert in the Ernst-Happel-Stadion. The Room is located near to bus and U-bahn stops, making it very easy to commute to the stadion or into the city.
Only flaw were the train rails and large street below the window, which is quite noisy if the windows are kept open. For us it was totally fine, but not recommended for noise sensitive people :)
