We had a great stay at Marga's apartment. The apartment is beautiful and has a great view of the Sol neighborhood. We also really appreciated the Madrid tour books and personalized tips she leaves out for guests. The location in Sol is great, the perfect central hub for exploring the city. Every place we wanted to visit—other neighborhoods, restaurants, museums, parks, the palace, etc.—was a short walk away. Because it is right in the heart of Sol, it could be a bit noisy, but that should only be an issue for the absolute lightest sleepers. With the windows closed, it was fairly quiet, and Marga has thoughtfully supplied earplugs for anyone who might be especially sensitive to noise. Marga's team was also very communicative and helpful. I'd definitely recommend staying at her apartment.
