The only issue I have is finding the carts sometimes. They aren’t always in the front even though the sign says return it to the front; sometimes they are in the hallways. So just look around!

Juste wanted to say that Roland, made my day, by being kind with a smile and was really listening to my situation !!!!! I know we all are going through some rough times at the moment with this carona virus!!!! Sometimes a smile and being treated like a real person from strangers is all i need to get through the day! So thanks for makin my day!

I have had the best experience here! This place is so clean, I don't see spiders or webs anywhere, ants and thankfully no rodents. They stay on top of this place! They are very reasonably priced. A lot of places when looking for storage charge rediculous prices! When I found cube smart in diamond bar, i was so grateful, the prices for the space, the whole property is clean, security has been great, customer services and management »» AMAZING!! They are always polite, respectful, they make an effort to remember you and you can't find that type of personable experience anymore! They help you understand your bill if need be and any other information you need! This place is 20 minutes from where I live and I don't care, I'd rather drive 20 mins to get the customer service they provide and for the reasonable price I can afford for my storage!
