Cesar's pad was a gem. With a head to toe refurbish, the space was light-filled, fresh and modern (great bathroom, powerful A/C) while retaining old world architectural details and charm. The balconies overlook a dynamic street leading into one of Madrid's hippest neighborhoods and the apartment is centrally situated for launching any Madrid explorations. And Cesar is a fantastic host: communicative, helpful with suggestions, flexible with calendaring.
I definitely recommend this home for your Madrid adventure.
