Terrific is the word that comes to mind in describing our experience at Nader's flat. The welcome and orientation provided by Nader was terrific as was his follow up communications and responses to e-mail inquires during stay. The apartment is terrific, clean and European modern accurately described in the photos. The location is terrific, a block from the metro and three blocks to a park with Templo de Debod which provides a spectacular sunset backdrop and the cable car. From there it is a pleasant walk to the palace and its gardens and on to Plaza Mayor. A map orientation from Nader on arrival will save many steps and metro stops. If prefer the "hop on hop off" it passes in front of flat. The neighborhood is terrific; safe and providing food stores , fruit stand, bakery, restaurants, cinema, etc.
While we had positive experiences at all 3 Airbnb's we stayed at in Spain, Nader's was the best. On the last day Nader arranged luggage storage while we completed site-seeing and reasonably priced transit to airport.
