I didn't notice any elevator. It is a two story motel.
But be aware that if you check in before 3:00, they will charge you $20 for the prevledge of "earily check-in". I arrived at 12:15 and was ready to check in, my room was avaliable, but the front desk clerk require $20 for earily check-in beofe 3:00. I came back at 3:00.
