I can't rate Andres's place highly enough. First off, he's an incredible host! He was extremely helpful with local information, gave a great tour of the apartment, and even provided welcoming snacks and drinks! The apartment itself is such a gem. It's located in the most perfect location imaginable for Madrid: right next to the palace and the opera house, extremely close to metro stops, and no more than a half hour walk to so many attractions like the Prado or the Reina Sofia. The bed is upstairs in the loft and is super comfy! The bathroom and kitchen are great. The wifi is good and you get a bunch of channels on the TV including some in English. The sofa folds out and is also really comfy to sleep on - I actually crashed on it the first night I arrived! I don't really know what else to say, but hopefully this glowing review has made it clear this is one of the absolute best spots in Madrid to stay!
