We had a wonderful stay at this flat. Our unit was a penthouse duplex with a rooftop terrace that overlooked the city. The flat was spacious, modern and in a great location. We were a 3 minute walk from the Reina Sofia Museum, and a 5 minute walk from the Atocha train station, which we walked to with our luggage, when we departed the flat. The other main tourist destinations in Madrid were all within a 20 minute walk. The host, Luis, was very helpful prior to our stay. He answered all my questions within a few hours. I would definitely stay here again.
