This is a great facility, it's my first time using a storage locker and they have made everything simple. They are responsive, the facility is clean and easy to use. I'm extremely happy that I chose here to store my stuff. I read the reviews below and was able to lock in my price by paying for a year in advance. ... Read more

PLEASE SAVE YOURSELF. In addition to WILD price hikes, this operation locked us out of our unit for 11 days with no subsidy or reduction of our wildly inflated price. We had a mover scheduled for the day the facility was supposed to open (3/24) and the doors did not function. Nobody answered the phone. We had no choice but to send the mover home. Upon discussing with "management", ZERO accountability was taken or any consideration given to the massive inconvenience and cost this incrued for us. What an absolute joke. There are much better options available. ... Read more

This is long but PLEASE READ!! 3.5-4ish stars Initially found a deal online for a 10x20 for $89 (with the lowest insurance i was offered-$26), this place is a bit further away from me but decided to sign a contract with them for the price. 3 months go by and then I get a rate increase letter by mail, making my rate jump all the way up to$152!!! That is a $63 price jump people!! I wasn't very pleased to say the least...I spoke with Steven over the phone a few times and we figured out there was a bit of miscommunication along the way, as I was originally told to pay in full to lock in the price (as I definitely DID ask about rate increases before I decided to go with them- to me it seemed like they were downplayed and seemed to be uncommon, still i asked how to avoid that) then when calling back ready to make the purchase another person told me that it wasn't necessary to lock in the price, I also was never informed that the nice promotional price you will see online EXPIRES (thats information you have to ask specifically about). I was starting to feel as though I fell for a scam, but Steven was able to help me get back to the original agreement price, I got locked in for a year starting today and I was able to pay in full without any worry about the unit for the next year. Giving 4 stars for the price of the unit (BEFORE the rate increase), well kept facility-climate control and decently cleaned, and for Steven's customer service! (If not for Steven's intervention this type of company would receive 1 star for how they seem to conduct business) This place loses a star (or 2) though due to, lack of parking (i had to park in front of a unit before since the limited spots were taken), 1 elevator only, I haven't seen a bathroom? (there probably is one but not in plain sight), one time out of a hand full there were no carts in sight, and MAINLY, because the rate increases seem to be a common trend...my advice would be to be what I did (even if someone tells you that you don't have to!) PAY IN FULL! It will only keep your price adjusted for the contract length, but its a good deal if your able to do so and only need the place for about a year. If not I would honestly recommend finding another storage unit that is a bit more transparent with pricing and doesn't have promotional pricing that expires. ... Read more

Vernon Avenue include the following amenities: Climate-Controlled, Indoor, 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Parking, Credit Cards Accepted, Elevators, Multi-Level Storage, Online Payment and RV Storage. Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

This particular storage facility provides self storage units of different sizes, ranging from 20 to 880 square feet. Space is not an issue! If you have more belongings to store, or simply bulkier items or even vehicles, you should go for larger storage units.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Monthly prices for units offered by Extra Space Storage - 999 West Mt. Vernon Avenue start from $27 and can go up to $1,147 for larger spaces.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
