North Beach Mail Boxes At Doo Wash

This is cheap — $ 150 for a year, and I think $ 20 per month if you want to go month-​to-​month. They’re open from early in the morning until late-​ish in the evening, except on Sundays, when they’re open until only 2 pm. You can have UPS, FedEx, or just about any other kinds of deliveries there — no more «Sorry we missed you!» notices or packages stolen from outside your front door!
Stanley and the women who also work there (I believe one is his mother) handle packages, and will place notices in your box if you get a package too large for the box. They accept credit cards as payment, so it’s all good. There is metered parking right in front of the cleaners/​mailbox place, but if those are filled, you can just park across the street for a minute or two (you’ll almost certainly be blocking someone’s driveway, so don’t dilly-​dally)! All-​in-​all, cheaper than anywhere else I’ve seen, great service, and a prestigious North Beach address. What more could you want?
