Since Red week is a site where owners post there units for rent I would suggest, for your protection, that you inform the owner that you would like to use Red week's escrow service. It cost, I believe, about $100 for the service which, if the owner agrees, can be split between the parties. You would provide the owner with your contact information, the owner contacts the escrow service, the escrow service works between you and the owner to get the rental agreement signed. Your rental fee is held in escrow and not paid to the owner until after you have completed your stay.
