I couldn’t be happier with my experience with this storage facility! From start to finish, the service was exceptional. Annie was friendly, professional, helpful, and attentive, making the entire process smooth, easy, and stress free. The facility is clean, well maintained, and secure, which gave my sister and I great peace of mind knowing our belongings were in good hands. Annie went above and beyond to provide excellent service, she made us feel welcomed and appreciated, and her professionalism really stood out. I highly recommend this storage facility to anyone looking for a clean, reliable, and trustworthy place to store their belongings. Excellent customer service, a great facility, and an overall exceptional experience!

Thank you for sharing your experience and recommending Extra Space Storage Anemone! We are glad to hear that the facility met your needs and that your move went smoothly. We will be sure to pass along your kind words to Annie and the team for providing helpful and attentive service.
