Was super fast and easy. I was able to reserve my unit and price on-line. They called me the next day to see if I wanted to get/setup my unit over the phone or online. But because I had already withdrew the money I want able to that; plus I wanted to see the unit first. Only thing is the office is closed on Sunday so I had to wait until Monday. Customer Service and Staff are very friendly, courteous, professional, and patient. Thank You. ... Read more

I had my unit for almost a year. The costumer service is good. I did get an online deal but sadly after 3 months of use they raised it $30 dollars which was disappointing. At this point I couldn’t move my items. The only issue is that they have very limited carts and people don’t put them back so you’ll find yourself looking all over the warehouse to find one. Just keep in mind that if you store on the second floor the roof leaks and causes moisture in the units. They have containers catching the water that leaks from the roof all over the 2nd floor. If you have moisture sensitive items I would consider storing elsewhere or the 1st floor only. The lift is very sensitive. You have make sure you follow the instructions properly. Overall it’s a safe warehouse and extremely convenient. It’s close to the freeway and trolley station. ... Read more

I rarely write a review, but this is one that I found fitting to write because of the Exceptional customer service provided by Ms. Ruth. When you feel like you’re carrying the weight of the entire world on your shoulders, she has a calming demeanor and will find a way to put a smile on your face. I am giving Extra Space Storage a 10/10 rating only because of this Angel. I will recommend this storage facility to anyone. I am grateful to Ms Ruth for showing me that even on your worst day, you can still find something to be thankful about. ... Read more

These amenities include Indoor, Drive-Up Access, Retail Available, Onsite Manager, Security Camera, Gate, Parking, Credit Cards Accepted, Elevators, Multi-Level Storage, Online Payment and RV Storage. 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 - 525 West 20th Street can satisfy all of your storage needs. Different sizes here range from 24 to 425 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.

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!
