Storage Customer Reviews

Lia Alyssa

"Just rented a unit at 21st Century Storage. Got a coupon for 20% off a Budget Truck. Will give it to my sister. My storage unit was very clean and new. Lowest price in the area." - "Very nice staff & very clean office and grounds. I'm impressed." - "I searched Philadelphia for the lowest prices and found 21st Century Storage. Other companies offered specials for free month, but none had the Totally Free Move In like this company. I'm very happy with the facility and the price." - "Budget Truck was easy to pick up. Staff was very friendly. Overall it was a great experience, I will recommend them to friends." - "I live in center city but decided to store here because of the Totally Free Move In special and low monthly rates. There was no contract and the facility is immaculately clean. Its worth the extra 10 minute drive, just go when there's no traffic." - "A+ company. Professional, friendly and super clean. I've used storage before, but none this nice. The office is 5x bigger than other self storage offices and is full of bright displays and packing supplies on sale. The prices for storage units are the best in the area and I will definitely be telling friends about it."

As soon as I arrived into this facility I was greeted by a kind young gentleman. This young man made everything really easy for me. I must say I have stored at several other places thoughout my years (Public Storage, Extra Space, Cube Smart) and I never received even close to the amount of customer service that I received from him. He even went so far to help me move my boxes in. I only had my granddaughter with me and it definitely could have been a hassle. The facility was really clean, I had seen an older hispanic gentleman going in and out th aisle sweeping and mopping. The vibe this place has is really welcoming. The only thing I did not like too much was there hours since it stops at 6pm. It's hard for me because my only way around is my son who works until 6 pm most days, if not my niece who just recently started driving who was with me the day of my move. Thank you guys, for the great experience but hopefully my items won't be there too long. However, for the time it is I couldn't have picked a better place this time. Sincerely Mrs. Simpson

This was my first experience with using a storage facility. 21st Century is great. The customer service on the phone was wonderful. When I got to the actual facility it just go better. If you are looking for a clean and secure building with a knowledgeable staff, go to 21st Century. Ask for Adam he is the absolute best.

Initially I picked it because the price was good and when I went to visit the people were nice, that's one thing I can say the people who worked there were always nice and helpful the problem was everything else. The roaches were out in force, the price for my unit changed and they only wrote a letter to an old address despite having both my number and email so I called when I saw the payment was higher and they explained they sent a letter months ago while I was out of state. Also the doors that led outside didn't work half the time so moving big stuff out was a task.

They will lure you in with a great rate and make you think that it's worth it to travel to the godforsaken wasteland in which they are located. It won't be worth it for long. Short-term rentals, fine. Buy my rent doubled in under five years. The last time I visited my unit, I found mouse droppings in my things. I called to notify them that I am vacating on the second and they told me that my contract ends on the 30th, and therefore I must pay an additional month to cover the TWO DAYS that my belongings will remain in the unit. I have never been happy with this place. I would say avoid them at all costs!

I would never recommend this facility. My furniture has been there less than a year, as I was moving out I began to notice that all my boxes and wood furniture has a layer of mildew on them. My grandmother's rocking chair will have to be refinished as well as my butcher block cart that has black mold on it. Walking down the hall to my unit, I saw a dead baby rat on Saturday it was still there rotting away on Tuesday when we took our last load out. As I swept the unit for clean up, all I swept up was rat turds. I'm very disappointed in this facility. Never go there......ever! Yes, i have photos of the mold, mildew, rotting rat, standing water on the floor and other disgusting things from this place. Also, they don't prorate and return your unused rent....there went $31 I could haves used for groceries for my kids. And being disabled the access to most units was ridiculous. The walk itself wore me out!

Worse place to rent from. I had my items stolen from there and the management there are ghetto as hell. Did not want to help me with my issues. All the five star ratings is from the management team and the owner so don't believe what you are reading here .

Whatever you do DON'T rent here! This is not for people who want to store stuff from their house. A car maybe but your stuff will be destroyed! All of my furniture was eaten by rats and kids clothes got wet and moldy. Then you pay for insurance but after months of waiting they tell you you can't get money to replace the stuff cause it look like stuff can be cleaned. I don't want that stuff no More! Then the customer service is terrible. I had to wait for almost 10 minutes before the guy sitting on his phone watching tv decided to ask me what I need, in those exact words. After I told him what happened all he said is I can tell you now they won't cover that. He told me to take the my stuff with me or they will continue to charge me rent and if I'd don't I will pay a trash fee of $100. I asked if he was joking but he was not. He said that's all he can tell me before he went back to his phone call. For all of the money I pay all of the service should be good but not the case. They are nice on the phone but that's it. I don't reccomend.

Finally got out of that slum of a storage facility.... paying for insurance there is a waste. They gave me a hassle when I tried to use it over water damage to my unit. When I moved out a good third of my stuff had to go into the trash due to black mold... Sick of dealing with the manager there as well as the cocky district manager.... Now all photos and information are with my attorney.... just so they don't get away with doing this to another tenant again. The entire lower level smells like a swamp from all the leaks.... Contacting Licenses and Inspections as well to see how bad the structure actually is.... Beware renting here you will lose your belongings unless they are sealed in water tight containers.
