    I needed some storage to assist with the sudden passing of a family member. It was a very tragic situation and this was not something I was looking forward to. I found that the ability to sign up for storage online was extremely easy. I have ample space. The cost is reasonable. And I wanted to pay a special compliment to Galen the site manager at the El Cajon facility on East Main street. I had several questions since I've never used a storage unit before and she was extremely professional, very thorough, easy to understand, and really the epitome of customer service. She helps make the entire experience that much easier. Very grateful. ... Read more

    Sign up was quite easy and the storage units a good value for the size. Access to the unit was also quite easy once I found where it was at.
