Read some helpful reviews of Extra Space Storage at 56 6th Street, shared by real renters with genuine experiences and honest opinions.

Prepare yourself for completely unreasonable price increases!!! Staff is very rude. Extra Space has nearly TRIPLED their monthly fee in less than a 6 months VERY DISSATISFIED. PS: They'll trick you with the low price in the beginning, in few months they'll jump up the price more than double ... Read more

The staff that works here are very understanding and so nice. If I was able to give them 10 stars I would have, they deserve raises for how much they go above and beyond for individuals renting a storage space. ... Read more

Finally moved the last item from this location. Have been renting here for over 20 years, more than 15 in the same 10X20 unit. Last year I mentioned E/S had raised the rent to $265.00 a month, one year later its $334 a month! So after raising the rates almost 100% in 2 years, E/S just tacked on another $69.00 increase in one year. Advertised web rate is still $220 - $240, I guess they hope you are on auto pay and will not notice the constant increases. Do yourself a favor and pay the extra dollar a month and have them send you a bill. Of course they have done some improvements, they added fire extinguishers, and still have a big beautiful weed filled hole where the old building used to be. Gives the place a nice abandoned factory feel. Nothing I like better than a large corporation coming in and buying independent business, then colluding with other large business to price fix rates. In the matter of a year the rental rates went up 96.2% from the previous business owners rates. Then tear down a landmark building which housed indoor storage and the management office, and leave a gaping hole/mosquito breeding pond in its place. Their excuse for the rates other than "corporate sets the rates", was, its matching other facilities in the area.....corp speak for price fixing. Reviewing rates via storagearea.com sets the average for a 10X20 at $212.00, so the $265.00 they now charge must make sense to someone. I guess they know how much of a pain it is to move, so they have you by the short curlies. Looking at the reviews further, it is evident they have not been looked at by Extra Storage recently. They talk about climate controlled storage at that location, yet they tore that building down. Their web pictures still show the picture of the office...not there. I am still trying to find out what justifies these rates. While the old owners were not perfect, at least they were one site. ... Read more

9/10 reviews are requested to be made before you actually have an experience with them. I and my husband rented a small unit last year which was short lived due too unexpected construction needing to be done. That’s fine an well we understand things happen. However due to the inconvenience we and many others were asked if we could get our belongings out by said due date that we would be refunded a certain amount and here we are a year later and multiple phone calls still with no refund. Manger Tanya was very rude and snarky and unwilling to listen disregarded the fact it has been a year and people who keep saying they will fix the issue as well as being told their was check already expected to be sent out just to find out none of that was true. So frustrating dealing with the unprofessionalism we have to deal with in todays world and people who lack people skills working in a position that holds such power. ... Read more

Joel helped me book the storage space rental initially and he was a huge help! I virtually booked the rental online and he called me within 20 minutes to finish the booking process in a stress-free, and quick manner. He was very helpful and descriptive throughout the whole process and gave me insight into the latest offers and deals they were providing (first month completely free!). After I know longer needed the storage space he canceled it for me on the spot so I know longer would be charged. Overall he was a great help! ... Read more

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 - 56 6th Street can satisfy all of your storage needs. Different sizes here range from 50 to 300 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 - 56 6th Street come at a variety of prices, starting from $75 per month for typically smaller units. However, larger spaces can set you back up to $348 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!
