Wolf's place is great if you have never been to Vienna. The metro lines from the train station (U1) and Wien-Mitte (U3) where you connect to the SBahn and airport trains are as close to his place as the Cathedral is from the station--and the stops are named after the cathedral. Other than the shower which is a bit cramped, the apartment has great spaces, heating, and is extremely quiet. It was great being so close to home no matter what place in the Innere Stadt one visited. Price was rather low for the location, so book if you can find it. The washer/dryer and dishwasher were nice touches as well, as were the five English speaking channels on TV.
