It was a great little apartment in the center of Malasagna district. Close to all the action, yet very quiet at night. We didn't meet Rafael in person, but he was very quick to respond to any questions we had before the visit. His friend Jose greeted us at the airport and drove us to the apartment (for a fee), gave us the keys and explained all the best spots and eateries around the neighborhood. The balcony/terrace was amazing! Great spot for a breakfast in the morning or a dinner in the evening, soaking up the sunset and the noises of the city hustle below. Kitchen had everything we needed and Rafael provided us with a baby cot for our 1 year old upon request with no additional fee.
We are definitely recommending this apartment to anyone, who is going to Madrid and wants to be in the walking distance from all the major sightseeing place, plus the local life.
