I had an excellent experience at this Public Storage location, thanks to Tsegab and Carlton. From the very first day I opened my storage unit, they have always been helpful, professional, and kind. Today, when I arrived and there was ice in front of my unit, they immediately stepped in to help me without hesitation. Their customer service is truly outstanding. They go above and beyond to make sure everything runs smoothly and that customers feel supported. I am so glad I chose this location for my storage needs. Highly recommend! ... Read more
So-fun F. - 28 January 2026
I've been with this PS for 20+ years. This year my rent went up $100 a month to almost $500 a month. I knew it was a long shot but I went in to ask if anything I can do for a decrease, based on how long I've been there. Carlton, the manager there was fabulous. He was patient with me as we looked at solutions and keeping my unit with PS vs having to relocate all my 10x15 unit. PS did keep my current rate for six months, so no increase, and Carlton helped me reserve a new unit just four doors down from my current one, so while I have to move things - it's a good thing as I need to organize and purge - and saving almost $300 a month with my rate increase. Carlton was patient, and thoroughly explained everything and went above and beyond to ensure my new unit was near my current one, making the upcoming move easy. I was ready to move to another facility at around the same cost as my new rate, and am so happy that I won't have to go that route. I'm only giving this five stars to Carlton and his amazing customer service, not only to me, but to other customers I saw him interact with while I was on the property. I don't like some of PS policies and I don't like their $100 rate increases, but I do like Carlton and will stay because of him. ... Read more

I had the most helpful and courteous experience at the Public Storage location on E Diamond. We are a retired military family who have had the need of external storage on/off for the last 20yrs. Thru out those years it’s just been short direct to business customer service. But as of today we experienced exceptional customer service by Carlton and his co-worker (sorry I can’t remember his name at the moment) but he was equally exceptional. What made it exceptional was the compassion and non judgmental attitude towards our situation of feeling overwhelmed by needing space again after all these years. It might not mean a lot to most people but good help is hard to find and even more rare these days are engaged staff. Hats off to the 2 great employees at Diamond Rd in Gaithersburg your attention to details and approachable attitude was well received and I hope other customers take the time to acknowledge your efforts. ...

Responsive employees to answer questions and help sort out moving to a new unit, fast service and easy moving process. They gladly showed me around the facility to locate alternate loading points and to find carts for fewer trips, highly recommend! ... Read more
Lindsay R. - 21 August 2025
I was having a horrible day when I decided to go to Public Storage. Carlton turned it all around with his positive and helpful attitude. He gave me options on choosing the right unit and even looked online at other Public Storage units in the area to better help me. He made my experience enjoyable and easy. Wendy his co worker was also very friendly and accommodating. Public Storage needs to have employees like Carlton and Wendy at all there locations. ... Read more
Don C. - 27 July 2025
The staff was great, highly professional and they were honest and detailed oriented. I would recommend this public storage to friends and family openly. I was assisted by Carlton and he was a true professional and provided excellent customer service and made sure I was clear on everything and provided excellent recommendations. ... Read more

I had an absolutely wonderful experience at Public Storage, thanks to the exceptional customer service provided by Tsegab and Wendy. From start to finish, they went above and beyond to make sure every detail was handled with care and precision. Both were incredibly knowledgeable, professional, and genuinely kind. They made the process smooth, stress-free, and even enjoyable. It’s rare to find such attentive and thoughtful service these days, and I truly appreciate the extra effort they put into ensuring everything was perfect. I highly recommend this location — and a big thank you again to Tsegab and Wendy for making it such a positive experience! ... Read more

This has been one of the most frustrating experiences I’ve encountered. I have rented 2 spaces in this location and 1 of it is on the 3rd floor, and when I arrived to drop off 8 boxes, the elevator was out of service. The storage manager suggested I carry the boxes up the stairs and assured me they would notify me once the elevator was repaired. However, I never received a follow-up call. Four weeks later, after hearing nothing, I returned only to find the same issue. Finally, after 12 days, I received a voicemail stating the elevator was operational. Yet, when I went back, it still wasn’t working. I’ve left multiple voicemails because no one asnwers the calls and since then with no response. This ongoing issue has caused significant delays in my moving process. I need someone to call me ASAP ... Read more
Shahan A. - 15 November 2024
This was my first and last time renting something through the internet without looking at it first. As you see in the pictures, this building is not cart-friendly. If you are planning to store large furniture or boxes, be careful because you have to go through doors. These two things are my biggest complaint; it is extremely hard to use the carts when fully loaded because of the edges and a pain in the * go through the doors with large furniture. They called me right away when I posted my initial review, asking me if there was anything they could do. So at least customer service is good. ... Read more

The storage units offered by Public Storage - 501 East Diamond Avenue can satisfy all of your storage needs. Different sizes here range from 25 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 Public Storage - 501 East Diamond Avenue come at a variety of prices, starting from $47 per month for typically smaller units. However, larger spaces can set you back up to $540 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!
