I had an excellent experience thanks to Hayvette at Extra Space Storage. She went above and beyond to make sure I found the right unit to fit all of my valued possessions. It was clear she genuinely cared about my needs and took the time to guide me through the best options.
Extra Space itself was great to work with—they offered strong promotions and were very accommodating, which really helped ease the stress of my move. The whole process, from selecting a unit to getting set up, was smooth and seamless.
Hayvette made everything feel easy and stress-free. She was kind, patient, and extremely professional throughout the entire interaction.
I highly recommend both her and Extra Space Storage if you’re looking for great service and peace of mind!

I had an amazing experience thanks to Heyvette at Extra Space Storage. From the moment I walked in, she went above and beyond to help me find exactly what I needed. She didn’t just point me in a direction—she actually took the time out of her day to walk with me and show me different options until we found the perfect storage unit for my situation.
Her customer service was truly outstanding—professional, patient, and genuinely caring. It’s rare to come across someone who takes that level of pride in helping customers. Because of her, the whole process was smooth and stress-free.
If you’re looking for storage, I highly recommend working with Heyvette. She made a big difference, and I’m very grateful for her help!

I started using a storage unit when I got pregnant and needed to prepare our third bedroom for our new addition. I don’t remember his name but the gentleman I worked with to set up the unit (he’s still the regular person there) was friendly and helped get everything set up for me so I wouldn’t have to worry about a thing with billing or management. He showed me my unit and got me fully squared away. Fast forward three years later, we have outgrown our townhouse and are moving out of the area. It was time to clean out and close the storage unit. Heyvette saw us cleaning out and asked us how we were doing and if we needed anything. She made a point to tell us exactly what we needed to do to close out the unit and made the whole process easy. We didn’t finish clearing that day but when I returned today, she remembered me and was so polite and friendly. She even offered to help me load the last couple of items into my truck as I was loading up alone this time! That is above and beyond what I would expect. She is so pleasant and friendly and made a point to ask about my daughter knowing that was why we got the unit. I highly recommend this location! That’s showing you truly care about where you work and the people you are providing customer service too.
This place has an excellent team in place.
