Gift idea for our maid?

I live in a dorm at college. Each floor has a maid who cleans our bathrooms and sinks, sometimes tidies our rooms for us.

My roommate and I want to get ours some kind of thank-you gift for the end of the semester.

Any ideas? I literally have no clue what to get her. I make very small talk with her sometimes if I see her in the hall on my way out or into my room, but I don't really know her or anything. She's a really sweet, older lady.

I just need some nice thank-you gift ideas that anybody (or maybe just females) could use or might like. Thanks!
