We had a pleasant stay at Natalie's unit. The house was just as advertised, located at a convenient walking distance from the public transit system. Opposite her bldg is a coffee chain for quick grabs and nearby is the Prater amusement park. Natalie was prompt with communication, responding to all queries patiently. We arranged an airport pick up through her assistant Walid, who also helped us with check in and gave us a download on the unit and on planning our site seeing itinerary. We had a happy stay in Vienna, thanks to Natalie.
