Thought this place was great until I got a letter in the mail telling me my unit is jumping from $139 to $212 next month. That's a 53% increase overnight. No warning, no explanation, just a huge hike out of nowhere. Textbook price gouging, reeling you in with a fair rate and then crank it once your stuff is already sitting inside. I'd think twice before storing anything here unless you want a moving target for a bill.

Angela & Alison have been amazing. Angela took so much time showing me different size units. She helped me set up my account & went over everything so thoroughly. Alison showed me all kinds of packaging I could use & both girls worked to find me the best size & deal Everything here is very convenient to access, clean & safe . All in all, I would recommend ES Storage to all in need of a safe, clean place.
