This looks like Steatoda nobilis, a Noble Cobweaver. They are in the family of spiders that make true cobwebs. They prefer to avoid people if they can. If this one was on the wall in a dark room when you turned a light on its reaction iwould be to run to a nearby hiding spot or hold still until the light is gone again.
