This Extra Space Storage in Alameda is a great facility. This storage is complemented with a really staff named Monica. She does an awesome job with customer service, plus the onboarding with getting a new storage unit is quick and easy with her. Thank you

I never had a problem with the staff and they were always nice and welcoming. The property was always clean and even when an elevator broke it was fixed in a timely manner. Would recommend to anyone and would use the company again.
