Ari is the perfect host: he provided us with plenty of information before our trip and answered questions specific to our stay (secondhand bookstores, Christmas markets). Always in a friendly & welcoming manner. Directions to his place/check-in could not have been easier. While we didn't need to contact him while in Vienna (the sign of a perfect apartment, more on that soon), he's quick responses in the days leading up to the trip left us assured that he would respond promptly. The apartment is, like others have written, simply perfect: clean, with all the necessary amenities, comfortable and fabulously located. We will gladly stay here again on our next visit.
