The Leslie Apartments was the name given to the former David T. Denny house, owned and occupied by David and Louisa (Boren) Denny. The home originally sat on Decatur Terrace, 512 Queen Anne Ave., just east of Queen Anne (Temperance) Avenue, and south of Mercer Street.

It was moved during the early 20th century to the southeast corner of Queen Anne Avenue and Republican Street. The structure is now torn down.
