Excellent service, no complaints
I've used a storage space with SPS in Bethesda, Maryland for almost 15 years while living abroad. They have always been super helpful over phone and email and on the 2-3 occasions I've had to interact in person, wonderfully pleasant. While they've had to raise their charges in that time like any other company would, I do genuinely believe that they've been rather controlled about it. The facilities feel secure and are very well maintained, in my view.
