    We had a wonderful experience at Extra Space Storage. From the moment we walked in, the staff was warm, welcoming, and incredibly helpful. The manager, Genevieve, truly went above and beyond. She took the time to walk us through the facility, discuss our needs, explain all of our options, and offer her honest recommendation on what would work best for us. She made the entire process feel easy and stress-free. The facility is clean, well-maintained, and well-organized, and the staff made us feel more like family than customers. We’ll definitely be long-term clients and highly recommend this location! ... Read more

    I cannot say enough great things about Extra Space Storage, especially Genevieve, the manager! From the moment I walked in, she made the entire process smooth, stress-free, and even enjoyable. She went above and beyond to answer all my questions, explain my options clearly, and made sure I felt confident and comfortable with my choice of downsizing units at an affordable price! Genevieve’s professionalism and kindness really stood out — she treats you like more than just a customer. She genuinely cares, and you can tell she takes pride in making sure people are taken care of. The facility itself is clean, secure, and easy to access, but it’s Genevieve’s amazing customer service that makes this location truly special. If you’re looking for storage, don’t waste your time anywhere else. Go see Genevieve at — she’ll take care of you! ... Read more

    Five Stars for Genevieve at Extra Space Storage I don’t usually write reviews unless they truly matter—but Genevieve, the manager at Extra Space Storage, absolutely deserves recognition. From the moment I walked in, she was present, accommodating, and incredibly helpful. I had been overwhelmed trying to figure out what to do with my belongings, but Genevieve not only helped me assess the right unit size, she also took the time to talk through my concerns—especially around protecting my property and feeling secure with my choices. She helped me organize my thoughts, upgrade my unit confidently, and understand exactly how much insurance I needed. I didn’t feel rushed or sold to—I felt supported. What stood out most was her genuine care. She was upfront about pricing, including upcoming increases, and that honesty alone made me trust Extra Space Storage more. She treated my situation like it mattered, and that kind of integrity is rare. When I first came in a few months there was someone else pushing for a review on the spot—and I didn’t appreciate that. This review is different. I’m writing it because I want to—because Genevieve is running this location with professionalism, heart, and transparency. Honestly, I wish every Extra Space Storage had Genevieve run more stores because this sort of support is very hard to come across. Most people just wanna get their job But Genevieve cares not only about the customer, but it’s obvious she cares about extra space storage as well. I really like this girl and I am Review because I really mean it not because I’m forced to.If you’re looking for a place where your belongings—and your peace of mind—are taken seriously, this is it. Give her a raise and a promotion—she’s running this place the right way. ... Read more
