Our flight arrived Madrid an hour early, 9 am. We took the express bus to Atocha station, which is near the apartment and museums. A transit station that's in a great neighborhood.
Next we walked ten blocks to the Apartments Las Letras, on Plaza de Matute. We are there by 11 and check in. A bored young woman sat at the hotel desk. The apartment was disappointing and, we'll discover, will tie for worst with the hotel in Evora. The window opened to a light shaft and the sound of jackhammers. The rooms were run down. The couch looked retro stylish like it was pulled from a '55 Cadillac, but small and hard and uncomfortable. No comfortable place to sit. The bathroom was modern and light though the toilet seat was loose, which we found to be a chronic problem among our choices of accommodations. There was also a sign warning no tp in the toilet. Great location though. Cafes, museums, Plaza Mayor, Puerta del Sol, all are just blocks away on pretty car-free or car-controlled streets.
After a rest we walked to a cafe for churros and coffee then explored the nearby squares. Dinner was pizza and pasta at a cafe nearby.
