We had a great stay at Chris & Max's in Vienna! Apartment is as described on website, and close to city centre (tram is a short walk away, but we walked most days - about 20-25mins to Albertina and other attractions. Both Chris and Max were easy to get hold of when needed, and were very kind - waited for us after we were late getting there from the station without phone working, and helpful when I left something by accident in the apartment after checking out. Would recommend again!
