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

    I had a great experience with Extra Space Storage. Although I ultimately didn’t move in because I found a permanent flex space for my business, the entire process, from reservation to my interactions with the team, was excellent. Everyone I dealt with was professional, helpful, and easy to work with. The facility was very clean, well-maintained, and easily accessible. Based on my experience, I’d absolutely recommend Extra Space Storage to anyone looking for storage space. ... Read more

    We have been with Extra Space Storage since they opened. We have had the best experience with Samantha. She will always do her best to get the best rate. And the location is so convenient. So glad we made the move. ... Read more

    This was by far the easiest experience I had for a rental! Signed a lease online, paid my fee (which was a steal btw) & was able to move in all in the same day, literally within a few hours. I was called before going just to make sure any questions I had were answered (much appreciated as this is my first time renting a storage). Very clean space! Loving my experience so far! ...

    Overall the best value and service you can get for a storage unit. I have had my unit since 2024 and had a brief question about my rate. The store manager Samantha was quick with the proper answer and went well above her means to ensure that a good standing loyal customer got the service they needed. A question turned into a better value and could not be happier. The facility itself is always clean and organized. It really does come down to “if you have a question just ask”. But other than that everything has been very straight forward and simple. Once again, an amazing facility and company. ... Read more

    Samantha was extremely helpful in selecting my unit. Definitely book an appointment to tour them! Very secure and they offer unit insurance in case of emergencies. It was really comforting to know that they complete routine unit checks to ensure everything is secure. Excited to know I’m storing at a nice facility and 10/10 touring and booking process. ...

    I had an amazing experience at this storage facility! From the moment I arrived, everything was clean, organized, and secure. But what really made the difference was the service — Evan was outstanding. He was professional, friendly, and incredibly helpful every step of the way. He answered all my questions, explained everything clearly, and made the entire process quick and stress-free. You can tell he genuinely cares about the customers. If you’re looking for a reliable storage unit with top-notch customer service, ask for Evan — he’ll take great care of you! Highly recommended. ... Read more

    I recently had the pleasure of using Extra Storage Unit in Wilbert Ave, Allentown, PA for the clean and well-maintained units to the secure premises, everything exceeded my expectations. However, what truly set this facility apart was the exceptional customer service, and in particular, the outstanding assistance I received from the Assistant Manager, Mr. George. From my initial inquiry, George was incredibly helpful, patiently answering all my questions and guiding me through the different unit sizes to find the perfect fit for my needs and budget. He was knowledgeable about the facility's policies and procedures, making the entire rental process smooth and stress-free. Throughout my rental process, George was always approachable, friendly, and readily available to assist with any questions or concerns I had. Whether it was a minor access issue or needing clarification on my billing, George handled everything with professionalism and a genuine desire to help. He went above and beyond to ensure my experience was positive and hassle-free. The facility itself is excellent – clean, secure, and easily accessible. I always felt confident that my belongings were safe and well-protected. But it's the human element, and specifically individuals like George, that truly elevate a service from good to exceptional. If you're looking for a reliable and well-managed storage facility with outstanding customer service, I wholeheartedly recommend. And when you do, be sure to ask for George – you won't find a more helpful and dedicated Assistant Manager! ... Read more

    Five Stars All the Way! We had an incredible experience with Extra Space Storage, and a big part of that was thanks to George! From the moment we arrived, he was kind, professional, and extremely knowledgeable. He answered every question with patience and clarity, making the whole process easy and stress-free. One of the biggest reasons we chose this location is because our daughter also uses the facility—and she’s had nothing but great things to say. Now we see why! The facility is immaculately clean, secure, and very well maintained. You can tell they take pride in what they do. And let’s talk about pricing—they beat everyone else hands down. We shopped around, and Extra Space had the best rates with no hidden fees or gimmicks. If you’re looking for a storage facility that’s reliable, affordable, and provides top-tier customer service, this is it. Ask for George—you’ll be glad you did! ... Read more

Did also speak to George as well quickly and he also was helpful and reassuring. Amazing and quick customer service which was much appreciated!!! Facility is brand new and unit is so clean and spacious for my needs. Climate controlled was definitely something I was looking for and found!
