4.8/5 - 663 Reviews

Read some helpful reviews of Extra Space Storage at 3400 Bayport Blvd, shared by real renters with genuine experiences and honest opinions.

We closed our account on Saturday, Sept. 28th with confirmation in hand. Since the office is closed Sundays, the system bumped the move-out date to Monday, Sept. 29th—which we never agreed to. We returned the lock and key on the 28th (our billing cycle end date) and called the next morning to confirm the account was settled. Later that evening, I received a call from a worker (Diana) who was immediately rude, dismissive, and threatening. She claimed we now owed a full month’s rent ($151) because the system showed 9/29 as the move-out date. When I questioned why my online confirmation clearly was able to select 9/28, she refused to listen and simply repeated “collections” over and over. My husband then called and got the same hostile treatment. She refused to speak to him unless he three-wayed me in to “authorize” him, even though he’s a registered account contact (which we later confirmed). Once she finally spoke to him, she suddenly offered that we could pay for just one day — but only in cash. That option was never offered to me, and a “cash only” requirement for a corporate storage facility is beyond questionable. When my husband went in person to the Seabrook location to settle this, he overheard Diana’s boyfriend sitting in the office, insulting us out loud with profanity (“those disrespectful motherfers”) while she laughed and agreed.* Completely unprofessional and unacceptable conduct. And the final proof of their dishonesty? The receipt they gave us shows the close date as 9/27. Meaning we were right all along, and all the harassment, collections threats, and cash-only demands were completely fabricated. This is one of the most unprofessional and shady business experiences we have ever had. From fabricated billing to harassment and profanity in front of customers, this location is an embarrassment to the Extra Space brand. Consumers beware: Do not trust this facility. They will manipulate dates, threaten you with collections, and treat you with open disrespect. Take your business anywhere else. ... Read more

Easy to get moved in! James was on the site and was very helpful and polite. The facility is very nice and clean. It’s a place I recommend to anyone that is looking for a place to store any of your possessions. Ask for James and he surely will take care of you! ... Read more

There is never a cart available. I walked the entire facility yesterday and not one cart was to be found. Before I signed a rental agreement I was assured there would be carts available at all times; carts were available initial move in but I have not seen once since. Also, my rent went from 145 to 225 and there isn't one additional benefit or amenity to warrant that type of increase and I've only been there about since April. ... Read more

I had an amazing experience with this storage company. I called and spoke to James, he helped get me set up so when I walked in it was a quick and easy process. He also gave me a promotional deal for a free month! When I got to the office, Dayna was so helpful! I actually needed a different size than I booked so she showed me the units and quickly got me what I needed and also found a promotion for me. I would recommend this location and company. ...

DayNa was AMAZING! She went over and beyond to make sure I got a good rate for my storage rental. They were having technical difficulties when my daughter and I went earlier in the day and she stated she would call me back later on in the day to finalize everything. DayNa NOT ONLY found me a good rate she found one at a different location. I thank her! Her customer service went beyond my expectations! Way to go DayNa and Extra Space Storage for EVERYTHING!! ???????? ... Read more

I have rented an INDOOR unit #1030 here for several months. I paid $122/m starting out. Now $156/m. Only to return here and find all my belongings covered in rat poop and pee. I do not recommend anyone to rent from here if you have valuable items needing stored. That $1,676.00 that I just paid for rats to live, poop and pee all over my belongs. ... Read more

Most of these amenities can prove to be very useful depending on what you need to store.

The storage units offered by Extra Space Storage - 3400 Bayport Blvd can satisfy all of your storage needs. Different sizes here range from 25 to 350 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 - 3400 Bayport Blvd come at a variety of prices, starting from $48 per month for typically smaller units. However, larger spaces can set you back up to $317 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!
