An acquaintance just offered to let us stay in his AirBNB place for free when we're in NOLA in a couple weeks. The place is super cute, historic, and literally on Bourbon St (the quieter part, though, which is perfect). We couldn't afford to stay somewhere with that kind of price tag attached if we were paying for it. He has a rather upscale lifestyle in general, so I'm having a hard time thinking of something that would be a nice way to show our appreciation but that I can still afford. He very health conscious, lives in NOLA in a different location, and is a world-traveler.

Any ideas of something that would be meaningful or show how much we appreciate his generosity? I'm stumped but want to make sure we do something thoughtful.
