The convent is right next to the Puerta de Santa Teresa where we walked thru from the public parking near the Parque de Rastra. Tip there are public restrooms in this unmanned parking deck. You will need coins to pay for parking.
The church is beautiful and was built on the spot where the Saint was born. To turn on the lights to view paintings feed the meters near the artwork.
The Sala de Reliquias next door houses the Saint’s finger and other relics. There are also public toilets here.
