No hotel or motel keeper shall be liable in any sum exceeding the sum of
  two hundred and fifty dollars for the loss of or damage to property of a
  guest  delivered to such keeper, his agent or employee, for transport to
  or from the hotel or motel, unless at the time of  delivering  the  same
  such value in excess of two hundred and fifty dollars shall be stated by
  such  guest  and a written receipt stating such value shall be issued by
  such keeper; provided, however,  that  where  such  written  receipt  is
