Read some helpful reviews of Extra Space Storage at 901 Middle Country Road, shared by real renters with genuine experiences and honest opinions.

I cannot say enough great things about Extra Space Storage, especially Genevieve, the manager! From the moment I walked in, she made the entire process smooth, stress-free, and even enjoyable. She went above and beyond to answer all my questions, explain my options clearly, and made sure I felt confident and comfortable with my choice of downsizing units at an affordable price! Genevieve’s professionalism and kindness really stood out — she treats you like more than just a customer. She genuinely cares, and you can tell she takes pride in making sure people are taken care of. The facility itself is clean, secure, and easy to access, but it’s Genevieve’s amazing customer service that makes this location truly special. If you’re looking for storage, don’t waste your time anywhere else. Go see Genevieve at — she’ll take care of you! ... Read more

I went to check out Extra Space Storage of Middle Island, and had the pleasure of meeting the manager Genevieve who was very nice, smart and calming; Moving and storage can be very stressful.

Five Stars for Genevieve at Extra Space Storage I don’t usually write reviews unless they truly matter—but Genevieve, the manager at Extra Space Storage, absolutely deserves recognition. From the moment I walked in, she was present, accommodating, and incredibly helpful. I had been overwhelmed trying to figure out what to do with my belongings, but Genevieve not only helped me assess the right unit size, she also took the time to talk through my concerns—especially around protecting my property and feeling secure with my choices. She helped me organize my thoughts, upgrade my unit confidently, and understand exactly how much insurance I needed. I didn’t feel rushed or sold to—I felt supported. What stood out most was her genuine care. She was upfront about pricing, including upcoming increases, and that honesty alone made me trust Extra Space Storage more. She treated my situation like it mattered, and that kind of integrity is rare. When I first came in a few months there was someone else pushing for a review on the spot—and I didn’t appreciate that. This review is different. I’m writing it because I want to—because Genevieve is running this location with professionalism, heart, and transparency. Honestly, I wish every Extra Space Storage had Genevieve run more stores because this sort of support is very hard to come across. Most people just wanna get their job But Genevieve cares not only about the customer, but it’s obvious she cares about extra space storage as well. I really like this girl and I am Review because I really mean it not because I’m forced to.If you’re looking for a place where your belongings—and your peace of mind—are taken seriously, this is it. Give her a raise and a promotion—she’s running this place the right way. ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that Extra Space Storage - 901 Middle Country Road has to offer. These amenities include Climate-Controlled, Indoor, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Elevators, Multi-Level Storage, Online Payment and RV Storage. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Extra Space Storage - 901 Middle Country Road can satisfy all of your storage needs. Different sizes here range from 25 to 551 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Extra Space Storage - 901 Middle Country Road come at a variety of prices, starting from $99 per month for typically smaller units. However, larger spaces can set you back up to $714 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
