Maintenance man came into my room by using his key to unlock the door while I was relaxing from a long trip. Assistant Mgr question me and made me feel cheap when she thought I requested a price match when actually the receptionist offered it to me. Two day stay resulted to two nights of loud noises and profanity frequently shouted from the room above me till 1am. Management's response childish and sophomoric.
