Since when did a bit of water ruin a carpet?
Run a wet vac over it until water stops coming off, turn the heating up and stick a couple of portable dehumidifiers in there.
Me, I’d be more worried about how much water has go in to and up the fabric of the walls, and what that’s doing to any structural timbers etc. Probably chasing out all the other water that makes its way up the porous formerly lime-rich sandstone matrix...
