Should I include a gym membership with my Airbnb?

[Mark Proctor]

I have a small Airbnb in a college town that is also close to several hospitals.  Our guests are mostly visiting because of those two things, and generally for 1 to 3 nights, but we do get the occasional longer stay.  Would it be worth it to offer a gym membership as an amenity?  The monthly expense would be a little bit more than what we charge for one night.  As far as I can tell, none of the other Airbnb's in our immediate area offer that.  I'm not sure our guests even want that, and I'm not sure it would increase bookings.  I was just trying to think of things that others don't offer.
