Raúl is by far one of the top hosts I've got a chance to meet through Airbnb. Not only he's extremely quick to respond, but he'll also assist you in anything you need during our stay.
He'll take the time to explain to you all you need to know about getting around in Madrid and will make sure no amenities nor anything else is missing. We had our breakfast supplies refilled everyday and he continuously offered help if needed.
The apartment is right next to a Renfe train station, one stop away from Atocha (the main train hub in Madrid). We will definitely stay again if we have the chance. Thanks for everything!
