Staying at Osman's flat was an excellent experience from beginning to end. He is very prompt in responding to any questions. Osman met us at the flat when we arrived and showed us around the flat. It was very clean and had everything you might need for a pleasant stay. The flat is in an ideal location, only about a 4 minute walk from the nearest metro station and central part of Vienna. I would readily recommend this Airbnb to any future travellers to Vienna.
