I only know where one church is and that is Parroquia SanAntonio de Pauda. It is located in Los Charamicos.
You can get there by walking along the beach. At the end of the beach the street to Los Charamicos starts and you just walk straight. 50 m down the road you should see the church on the right side of the street. I t should take 20 -30 minutes if walking. These are directions that were given to me.
I understand that they have a Mass in English.
