I was recently in the market for a mini storage unit in Seguin and called K-2 Storage. Turns out they are brand new and right in town about a block south of I-10 and Austin Street (next door to Patlan Elementary and across N. Austin from Home Depot). The staff is super friendly and willing to help and the facility is the nicest one I've seen in or around Seguin. Their rates are competitive, too. Overall I would rate my experience there excellent.
