A quieter and more peaceful version of the nearby Puerta del Sol. The cafes and restaurants around the square can get busy during the evening with locals popping in and having meals after seeing a play at the Teatro Español which is on the square. However the cafes and restaurants here are much cheaper than in the pricier Plaza Mayor. Just keep your wits about you at night and an eye on your wallet/purse as thieves do operate in this square and the surrounding streets as police do not patrol this area.
Nearest metro station: Sol
Plaza de Santa Ana is a 15 min walk from the Puerta del Sol and is best approached from calle Principe off Carrera de San Jerónimo
