The Casita is about four blocks from San mateo's commercial district and a roughly twenty minute walk from two different Caltrain stations. The space was very clean on arrival. We loved talking to our host, who was very kind, helpful, and accessible. The bed was comfortable and the kitchenette had a full sized refrigerator. There was ample storage for clothing etc. We were pretty pleasantly surprised at how much was going on in downtown San Mateo! We definitely recommend staying here if you find yourself in the Bay Area and want a convenient location to explore.
