We were extremely pleased with Jason's apartment, conveniently located to many of Madrid's best sites. We walked everywhere but also took the subway once which is just outside the apartment. There were good bakeries across the street for our morning coffee and bread.
The apartment was clean, calm, spare, roomy, and nicely decorated - most everything was new and well kept. It was air-conditioned and quiet at night with the windows and shutters closed but we also enjoyed sitting outside on the terrace at night to watch people walk up and down Calle Atocha and in the morning while having coffee (coolest times of the day).
Jason greeted us at the apartment, showed us how things worked, recommended a fun local restaurant, and communicated when needed. This was a great choice for a quick visit to Madrid.
