We are a family of five who just stayed in El Convento for three nights. I cannot imagine a more perfect stay. The equation for perfection is as follows:
1. The host and his helper are the most responsive owners/operators that we have ever met. They were incredibly helpful and responded to every communication promptly.
2. The apartment itself is beautiful and well-designed, as the pictures clearly show. More importantly, they have seen to every detail in the accommodations to make them exceptionally comfortable. Most importantly, it is the quietest apartment that you will ever visit in a major city. You literally cannot hear any street noises or sirens in this apartment.
3. The location of the apartment is perfect. Cava Baja is such a great street. Very photogenic with great architecture and lined with great bars and restaurants. We walked from the apartment to every major attraction in Madrid, including the Prado, Retiro Park, the Royal Palace, and Mercado San Miguel. You cannot find a better location.

All told, you cannot find a better place to stay in Madrid. This experience was the epitome of what makes Airbnb such a great offering.
