My wife and I visited Madrid briefly with our daughters. We thought Sol's apartment was conveniently located near the Prado Museum, El Retiro Park, and Puerta del Sol. It was located in a residential building with elevator. It was furnished nicely and included 2 full bathrooms, and plenty of hot water for showers. Sol went out of her way to meet us promptly when we arrived and was available by text or phone during our stay. I would not hesitate to recommend staying with her again.
