    "I live in downtown San Mateo. San Mateo is a nice place, but I have mixed feelings about it. There are many restaurants, grocery stores, and activities to enjoy. The bus and train stations are very close, which is convenient. However, I dislike that some people throw too much garbage or furniture onto the sidewalks. I believe it's very important to keep the neighborhood clean and safe. Another issue is the frequent theft of packages. I live next to the creek and often see homeless people entering through my building to access the creek. I don’t think that's safe. "
