Good location and the prices are different. They also offer discounts depending on your needs and length of stay which is great if you’re looking for long term rental. You’ll get peace if mind about your belongings being safe as the facility looks secure with unique access codes and security cameras all around the place. Shoutout to Jeremy for helping me out with my storage needs. Such a cool guy, took the time to give me a tour and show me different sized units and made the process very smooth.

Today I went to my Extra Space Storage office, in Belmont, Ca., to find answers to some questions I had regarding my storage locker and switching my monthly payment to a different credit card. The office manager was polite, friendly, and quite helpful in answering my questions and redoing my credit account. I was very pleased with how my interaction with the manager went. I give him a 5 star rating.
