The area I live in has a distinct smell that smells like ornate carpets, which I love.
I like rain smell, gasoline (very nostalgic car smell), and I used to study woodworking (and I like woodcarving in general) so any type of wood smells really good to me. And also freshly washed sheets of course.
I think I would rank them like so: Gasoline > Carpets > Wood > Sheets > Rain
