There's a Small Hotel — Elizabeth Cooke

There's a Small Hotel is a novel set in the Hotel Marcel in Paris near the Eiffel Tower. The narrator, an attractive American woman in her 60s, can see over the treetops from her balcony, a row of apartments, that when lighted from within at night, reveal vignettes of French domesticity, involving love affairs, violent dinner parties, fisticuffs, and the police. She becomes involved with the personalities within the hotel and across the street, and thrills to an unusual and exciting Paris sojourn.
