First, relax and assses the situation. A Guests Review needs to be clearly looked at because a Guest is a customer not a high paid consultant reviewing your rental.
1. Your flooring is new.
Was there a pet in the unit? If there was is there a possibility it was wet?
3. If you could of wet dog in your rental again was a wet dog on your floors for that amount of time to have caused a damaging smell? Not the usual.
4. Can you smell anything? You are looking for any unpleasant scent don't get focused on the adjetives describing a smell. Focus on is there an unpleasant smell? If yes, then first determine why may have nothing to do with the floors or new floors depending on the installation process did you rent when you had been advised to expect a temporary smell.
