Ronny was extremely helpful. I came near closing and was only planning to check out the unit because I didn't want to take up their time. He insisted that it wouldn't be a problem at all and before I knew it he hooked me up with everything I wanted and was extremely polite all the way through. I feel confident that my storage will be taken care of here and that the staff will be able to support my needs.

The unit at Extra Space Storage served my needs very well, and Ralph was great to work with. That unit was a life-saver when I really needed to place some stuff in storage for about a year, after down-sizing homes. The facility is also well-maintained and secure.

I found myself in a financial hardship and owed for a couple months.
The representatives were always friendly and explained my options and due dates in a friendly manner.
Ralph did a good job explaining the companies policies without making me feel bad or embarrassed about the situation. He was professional and demonstrated true empathy. The time Ralph took allowed me see that I will be able to get out this hole, not lose my stuff, and remain a customer of Extra Space for years to come. The pricing for storage space is very good as is the location. But employees like Ralph are what makes the company great and why I would recommend Extra Space to family and friends. Give that man a raise!
