If you want more than just a mailbox center or postal center, check out NoHo Mailboxes! Scott, the owner, is a super nice guy! We have been customers for over a year now and have had nothing but good experiences here. My husband and I own a private martial arts school just down the street and we are constantly getting packages shipped... Scott is super organized and always calls us as soon as the mail comes. He also does document printing, photocopies, shipping, greeting cards, etc, etc. etc.
Whether you are looking for a personal post office box or a business mail box, you won't be disappointed!
