If an innkeeper or hotel keeper provides a safe in his inn or hotel for the safe-keeping of money, jewelry, and valuable papers and articles belonging to the guests of such inn or hotel and gives notice thereof by posting in a conspicuous place in the office and public parlors of such inn or hotel the fact that such safe is provided in which such property may be deposited, and a guest neglects to deliver or deposit therein any such property to the person apparently in charge of the office, such innkeeper or hotel keeper shall not be liable for the loss of any such property sustained by such guests, unless such loss occurs through want of ordinary care and diligence of such innkeeper or hotel keeper.
