great on price

ive had this storage before, shopped around a few months and had different facilities and iam now planning on returning for a long time period. a bit farther from my house but i do not mind taking the trip because the price is the best.

Overall a good place

I got locked in after hours. I had to leave my vehicle on the premises. I had to use the emergency exit too get out. A warning in writing would have gave me a better understanding of the dos and don'ts...
