What is the story behind my landlady, the angel?

The story behind my landlady, the angel, involves a serendipitous friendship formed on Facebook, leading to an ideal London flat, and a surprising revelation that she was the model for a cherished 'angel' painting. The author, an American expat, met her landlady, also an American expat living in London, through shared creative work on Facebook. A mutual friend from Arizona further connected them. After admiring each other’s work, they met in person and formed a strong friendship. When the landlady’s job took her to New York, she offered her beloved London flat to the author at a great deal, solving the city’s housing crisis for her. The 'angel' connection was revealed when the mutual friend mentioned the landlady had modeled for a painting of an angel that the author had proudly displayed for years. This magical arrangement has brought the author immense gratitude and joy for three years.
