Sergio's place is in a wonderful location and a has a roof top balcony with fantastic views. We enjoyed walking around Madrid from the apartment. Retiro Park and Prado Museum were within a few minutes walk and although we chose to walk everywhere else there was a bus stop nearby and the Atocha train station, too, where we caught a bus to the airport. All correspondence with Sergio was prompt and worked well. We were met on arrival, and Sergio was very accommodating regarding storage of our bags around our flight home. Sergio - Thank you for a lovely stay.
