David is a great host. The whole place is simply great and easy to find. We had a great stay. The flat is in a quit neighborhood, it is near the metro station and there a lot of markets around to buy food from. Davd let us leave our luggage at his place before check-in time and after check-out time because we were leaving Vienna late at the evening. You won't make a mistake if you choose his place to stay at, i am strongly recommending him to everyone :)
