Stefan's house was in a excellent position, just minutes away from the main attractions (by public transport and by foot). It is a classic Vienna apartment in a old building with some interesting Jugendstil touches! Very clean, very quiet and bright. Note: to reach the apartment you have to take the appx. 120 stair steps since there is no elevator. (There was no problem for us, I just indicate this for someone who has mobility disabilities). Stefan was great as a host and very eager to answer all of our questions and gave us useful tourist tips.
