I am always dreading going to put my stuff in storage for the summer. The spaces are always sketchy and I’m usually confused as to how the unit even works. But this extra space storage unit in Ontario changed everything. One of the cleanest safest and quietest space I’ve ever been in and for such a reasonable price! When I got there I met the lovely manager named Jeff. He helped me figure out how to use the lift, find my unit , use the lock, and taught me how to use the app. He was so kind constantly looking after me and my friend helping us with whatever we needed. He also gave us refreshing cold water! This was the best storage experience I’ve ever had and I feel so safe being and leaving my belongings in that clean secure space. Thank you so much Jeff!

Searching for a storage unit can be stressful. Many storage companies have a lot of fees, contracts and high monthly fees. I did research online and came across Extra Space Storage in Ontario, CA. Jeff (Store Manager) was very professional and kind over the phone and in person. Jeff took the time to understand our needs and showed us 3 units to ensure we selected the right unit. Extra Space Storage offered such low month to month monthly fees. The facility is very clean and organized. Thank you, Jeff!
