I want to give you this sincere letter of recommendation to thank you for providing a safe storage facility for our business as well as personal belongings.  You have always given the very best customer service and the property is always very clean and well-groomed regardless of the weather.  When we needed a larger space you were accommodating and helped us choose a unit that was close to our smaller one which made it convenient to move the content.  

We were happy to refer friends to you when they recently moved to south Dayton and they have been extremely pleased as well.  Please use this letter of recommendation as our "thank you" and keep up the great work.
