Great location within walking distance to the Prado, Reina Sophia, Palacio Real, Plaza Mayor, Puerta del sol, metro, etc. Carlos was was responsive (best when calling, not text), and super welcoming when he gave us the keys. He even brought us some extra pillows and arranged our transportation back to the airport for our early flight departure. He was a a great first introduction to the warm Spanish people. The apartment is small but clean and had all of the essential amenities.
