    Read some helpful reviews of Extra Space Storage, shared by real renters with genuine experiences and honest opinions.

    This is not a safe property. They had a break-in on August 25, 2025 from 4AM-6AM. I bought this unit in May 2025. There was a worker who lived on premises and told me someone else would be moving in after. This led my husband and I to believe this property was secure. No one has lived on site since the former worker moved at the end of May. She also told us there was security, but failed to inform me that security stops working at 6PM. This means there was no security or anyone watching the cameras overnight. If we had been told truthful information, we would not have stored anything at Extra Space Storage. We were misled and it led to our unit being robbed, along with 4-5 other units. I would like to update to state that Ana (district manager) will refund the 3 unfortunate months we stayed at Extra Space. While on the phone with Helena, a team leader, I mentioned how I fault their staff Sammy, who misled us upon enrolling, Ana, and anyone who works for Extra Space (including Helena). She responds with, “I just got this. Thank you. Thank you for throwing me in there. “ in a very sarcastic tone. I reminded her that while she is being paid, I was robbed due to their lack of security. Don’t accept the term “lead,” if you can’t do so without speaking professionally. Another update: I spoke to the Detective on this case on 9/3. The detective from San Marcos Sheriff’s Department says this location has been targeted MULTIPLE TIMES this year. Helena claims they don’t have any reports of this from Sammy. Save your time, money, and stress. Avoid this place. ... Read more

    Extra Space Storage has exceeded my expectations in customer service! I had a poor experience with a previous storage place. Out of bitterness checked to see if there was something more affordable with safety and cleanliness in mind. We found it!! This place is worth the move!! Centrally located in San Marcos and recently under new ownership we called the 877 number on line got Anthony. He was a fast talker (my favorite) and explained everything. However there were a few things I had questions about that were specific to the location. Anthony gave me the direct number to the San Marcos storage manager on site. Francis, the on site Manager answered on the first ring! She is beyond knowledgeable with the ability to get us in with full transparency. Done and done! In a world going digital it's crazy to think that my experience with the customer care at Extra Space Storage has made my day.. :) Moving from my previous place this is saving me about 250$ a month for the same size unit with a 4 month pre pay start up. Thank you! ... Read more

    I spoke with an excellent customer service member by the name of Anthony who was more than willing to assist me in setting up my new storage unit. He was kind, friendly and very helpful in my quest to reserve a storage unit here. I had some extra questions regarding my own personal situation and he referred me to the site manager, Francis. Francis took almost an hour of her time listening and working out our issues that had resulted from the prior owners. I cannot stress enough how much of a breath of fresh air it is to speak to someone so empathetic, human and caring. Her one on one customer service experience set a bar that I am unsure anyone else can meet. Shout out to the manager Francis at Extra Space Storage for being transparent throughout the whole process and taking such good care of us as customers. I would suggest this business to anyone looking for a storage unit in north county, specifically San Marcos. ... Read more

    Honestly, the customer service has been AMAZING! We booked for a date way before we needed it because we wanted to benefit from an offer they had. But they honored the discounted price when we asked to push the start date. They kept calling to check if we need anything and we asked to modify the date twice and they happily did so. We also just got the unit, everything looks clean and easily accessible. ... Read more

We came in 15 minutes before close after calling to let him know we were on the way and he was more than happy to help make sure we were able to get moved into our unit. He also happily answered all of our questions. Our unit was clean and easy to access, while also feeling very secure. ... Read more
