    Joseph A. - 4 September 2025
    Outstanding experience thanks to Jon Lee, the manager. After using multiple storage facilities for our daughter's college belongings, this location is by far the best. Jon provided incredible customer service throughout. When we accidentally went two weeks beyond our contract with automatic billing, he personally secured a prorated refund. He's always available and truly goes above and beyond. The facility is spotless, secure, and climate-controlled with convenient access. Reasonable pricing, seamless move-in/out, and no hidden fees—just transparent service. Most impressive: Jon manages this entire location single-handedly while delivering outstanding support. Highly recommend! Perfect 10/10 experience! ... Read more
