As someone who lived in Madrid for a year, I was very picky about the neighborhood that I wanted to stay in while I visited for two weeks. Juan's apartment is in what I would consider the best of the best neighborhoods - walkable to so many great attractions (royal palace, museums, food markets), grocery stores, bars, restaurants, and shops. AND although it had amazing proximity, it was cozy and quiet, which is quite rare in a city where people are out at bars all hours of the night!
Beyond the proximity and calmness of the apartment, it was absolutely beautiful - super modern, quite big, large bathroom, and a wall of windowed doors that we left open each day we were there.
Thank you, Juan, for a wonderful place to call home for two weeks!
