We met Christian who was wonderful. Gracious kind and extremely helpful. As when we landed in Vienna we found our airline had lost my luggage. When our attempts to get through to airline failed Christian took over behind the scenes and shortly thereafter my found luggage was delivered directly to our room at Christian's address. What a relief. His place was lovely despite a few flights of stairs. Very modern, bright and airy. It was also incredibly peaceful/quiet in the inner courtyard where it is located. Very clean and comfortable. Also ery convenient to old part of Vienna in a cool older neighborhood with nice architecture, restaurants and a trolley stop extremely near by. Bought an unlimited metro pass for our 3 day stay and used the trolley as one of our site seeing options. Would definitely stay again.
