Mari Carmen is a great host - she was super friendly, helped me with my doubts, and gave me some recommendations for the few days I stayed in Madrid. The place is one stop away from Atocha and getting to the Subway is only 2 blocks away. Getting to Gran Via or any other place in the city has been super easy, and the apartment is 20 minutes away from El Retiro, El Prado and other attractions.
The place is spotless and the bed was really comfy, I was right at home.
Thank you!
