When I was preparing to sell my house I needed a storage space capable of holding everything I owned. The ExtraSpace location on Mariner Square Blvd in Alameda was perfect for my needs and wants. The person who helped me set everything up was Monica and she was professional, warm, knowledgeable, and very helpful, not to mention very patient. At a stressful time she came through for me and I couldn’t happier, satisfied, and relieved to have her help me. Monica and ExtraSpace Storage for the win!!!
