Niko was a fantastic host-- he was incredibly accommodating for our arrival, was always within reach for any questions we had, and the space that he created is thoughtfully and beautifully appointed (complete with chocolate and champagne on check-in :) The location is great-- first floor of a beautiful old building within a really pleasant walk to the Ringstrasse/Museum Quartier/Historic Disctrict/NaschtMarkt... or conveniently enough, down the block from the subway. The apartment is beautiful, modern, and very comfortable. Awesome home base for a visit to Vienna.
