Javier was the nicest and most hospitable host we encountered during our 2 week 4 city tour of Spain. He was always accessible via text (WhatsApp) and shared his favorite neighborhood restaurants. The apartment was well decorated, had all necessary amenities, and the location was great as it was close to the hustle and bustle of nearby Plaza Mayor and Puerta de Sol, and also walking distance from the Prado Museum and the Royal Palace. The apartment is on the ground floor so you can hear the street here and there, but luckily it is a very quiet off street. Javier was a great host, very accommodating, and I would recommend his apartment to anyone visiting Madrid for a few days.
