A transfer station for the Red Line 2 (between Sol and Santo Domingo) and the Green Line 5 (between Callao and La Latina), Ópera is in zone A as it is in central Madrid. It's right in front of the Teatro Real, and is close to the Plaza de Oriente and the Royal Palace.
The station has elevators from street level to the ticketing level and from the ticketing level to the platform levels. There are also stairs and escalators.
I learned later that the Fountain of the Caños del Peral that was uncovered during the dig has been preserved and is accessible in the station. read more
