This spot is convenient enough if you need to be in the San Mateo area and there's a convention in town that has nearly quadrupled the rates of surrounding hotels. It isn't the most comfortable place to stay, but it works.
One important thing to note; you won't be able to lock your bedroom door from the outside. When you leave for any period of time, your belongings are just sort of hanging out unprotected. If you're uncomfortable with leaving your things in a place where others are staying; this place probably won't be for you.
