We searched long and hard for the most reasonable storage within easy driving distance from home. CSI offered the best deal by far with not only their first two months discounted, but having our stuff moved for us for FREE! Then there is their regular monthly rate which is lower than any we found.
If there is a catch, it would be that the units are storage containers, not the standard storage buildings. But, honestly, the containers come in all sizes, are absolutely weather tight and are very easy to access and use.
The people who run CSI in Richmond are professional and a pleasure to deal with. We're super happy with our choice and give them a hearty recommendation.
