I had a great experience at Public Storage. The facility is clean, well-maintained, and feels secure. Adrian was very helpful and made the whole process quick and easy. He explained pricing clearly and answered all my questions. Definitely recommend if you’re looking for affordable and reliable storage!

Adrian was very professional and welcoming when I arrived and walked through the doors. He made it quick and easy to get a storage unit. Didn't take long and he also went out his way to find a unit that was more convenient for me and not stressful. Would recommend him to others and hopefully receives a reward for his hard work. 10/10 Service and Professionalism. Thank you Adrian!!

Had the most positive experience these past few days and made me feel like I was in a safe space. I would like to thank Adrian for making me feel safe and attending to all my needs and questions. This is the first time I rent out a storage and I had no clue how to manage one. Adrian explained step by step and was very detail oriented. Without his knowledge and assistance I would of been lost. Thank you Adrian for being a big help !! Wish there was more people like you in the world !! You made me feel safe !!

I wish I could give it 0 stars because that would better describe my multiple experiences with this location. FIRST: There is never anyone on site despite the office hours listed on website and on listing. At least two days each week there isnt anyone at this location even though ADRIAN lives above the office. When you call on those days and are forced to leave a message you then do not receive a response for 48+ hours. The app they force you to download never works to open/close the gate and they are never in the office, so how does one make anything work. You call corporate and they have absolutley no idea what is going on at each location. The whole system including monthly rates changing wihtout notice is terrible. When you do finally speak with someone, they never seem to know what is going on which is surprising to see ADRIAN receive such praise in the other reviews. ADRIAN is about as good at his job as the app functions properly.
