In 1941 she was assigned to the house at San Sebastian which had adhered to the Union since 1921, under the authority of a Mother General. From the first day she wished to act normally and be treated like everybody else. She became an assistant and teacher, a helper of the teacher in charge of the infants, a study invigilator, a portress at the tradesmen's entrance where provisions were brought and where the workmen entered the house.

She remained in this house until her death on 17th. January 1954. Her body was buried in the convent school cemetery situated in the garden. Later, her remains were brought to the convent chapel.

When news of Mother Cointa's death became known, a multitude of letters began to arrive in Donostia. The first letters of condolence were replaced by others which joyfully related the favours received through her intercession.

Typical of all who knew her was the fact that they regarded her as a saint and admired the simplicity with which she had acted in all circumstances. The quality which identified her was charity and the absence of anything extraordinary or sensational in her life, together with the value of the ordinary lived in an extraordinary way. It was not only the nuns who had regard for her holiness but also former pupils and friends.

Her sanctity was not one that was dazzling but rather something which, in an extraordinary way, shines through the ordinariness of everyday life.
