Location could not have been more perfect. You're close to an unlimited number of restaurants / pubs and just a short walk from the Gran Via. There are 2 A/C units, 1 in the living room by the balcony and 1 in the bedroom. There's plenty of living room space. We had a safe and quiet stay, even during a boisterous weekend. The apartment itself doesn't have a ton of furniture or art in it and is a little dark (as advertised in the photos) but if you're only there for a few nights and don't plan on hanging inside a ton, this is an affordable and suitable home base for exploring the Center of Madrid. Marta (host) is very responsive and made our stay very enjoyable.
