My wife and I stayed 2 nights in Harry's Vienna apartment. We had a great experience. The apartment was an easy walk from Wien Mitte station, where the airport train stopped. We had some confusion about the address, which was easily untangled by Harry, who was very responsive and available by text. The apartment was clean, functional, and cheery. The location is unbeatable: easy walking into central Vienna, to the museum quarter, and to countless attractions. There is a grocery store just down the street, which we would have appreciated more on a longer stay. Checkin and checkout were a breeze. We will definitely recommend this apartment to friends!
