Renan met me and my friends at the apartment - he was incredibly friendly, showed us around the flat, and even had a bottle of wine waiting for us. He was also very responsive and arrived to the flat within 10 minutes of us calling him with a question. The flat is in a great location, is finished nicely, and is equipped with everything you'd need - including aircon/tv/internet etc. I'd thoroughly recommend this place to anyone looking to enjoy Madrid, both Renan and the flat was fantastic.
