    I think it’s ridiculous that Extra Space Storage nearly doubles your rate after the first three months. These promotional rates are misleading when you end up paying significantly more just a few months later. On top of the pricing issue, I also had a problem with a skunk in my storage unit when I first rented the space. The facility provided no assistance or solution, leaving me to deal with the situation myself. That was a terrible first impression and made me question the level of customer service they provide. It’s frustrating because I was simply looking for a place to store my belongings, set up autopay, pay my bill on time, and go about my life without constantly worrying about price increases or having to deal with issues on my own. It feels like customers who are reliable, pay on time, and barely require anything from the facility are not valued. I ended up going to Stor-Um on Pacific Highway, where they offered me a larger storage unit at the same rate for an entire year, with no increase during that period. That is how you earn a customer’s business and build loyalty. I would much rather support a company that values its customers, provides decent service, and offers honest, predictable pricing instead of attracting people with a low introductory rate and then nearly doubling the cost after just three months. My advice is to shop around and compare rates before signing up. I found a better option elsewhere, with more space and predictable pricing. Based on my experience, I cannot recommend Extra Space Storage.
