We've done this a few times when we've been gone on vacation. Not sure we'll keep doing it, though. It's stressful, even with airbnb insurance, to lock up all your most valuable stuff, make sure your passwords are hidden, etc. It's also stressful, just as you're leaving on vacation, to also have to clean your house! And even having done all that, I've never really loved the idea of someone rooting around in all my personal-but-not-confidential stuff.
I would consider doing it again if we were gone for months at a time, but probably not for just a week.
