quaint

Attractively old-fashioned (but not necessarily authentic).

“houses with quaint thatched roofs”

Strange in an interesting or pleasing way.

“quaint dialect words”

“quaint streets of New Orleans, that most foreign of American cities”

Very strange or unusual; odd or even incongruous in character or appearance.

“the head terminating in the quaint duck bill which gives the animal its vernacular name”

“came forth a quaint and fearful sight”
