Hi Laura, what an interesting situation and can I say, I've been both sides of this one (as a guest and a host). Some guests use the space "lightly" and others, well, "really" use it. I think if there was actual damage, I would, as a host, do something about it. And as a guest, I would volunteer to repair. If it is a case of the space simply having been "heavily" used, I would suck it up and do the extra cleaning. I admit I've been one of a group of girls who have left drink rings, and overflowing recycle bins, used all the towels etc (nothing was damaged but we "really" used the place). As a host, I've had both sets of guests too. As hosts I think we have to accept that we are going to get guests who "really" use the space and while no damage is done, it's a pain in the *** to clean and reset. Swings and roundabouts I guess, because I've had some super easy cleans and resets too!
