As someone who's worked with over 10 different storage facilities, this is definitely one of the best storage places around! I absolutely love how the parking is facility parking is gated; I feel a lot safer unloading and loading my belongings into my car. The ladies that work here are awesome! Megan has, bar none, the best customer service! What a rockstar! She's patient with all the customers and you can tell she really cares about her customers and the community. Megan made my business here very pleasant and was very accommodating. They also have Uhauls you can rent directly from their lot! Extremely convenient and a life saver for me! ?????????? ...

I have edited this review after the staff brought it to my attention that this storage facility was staffed by service personnel and not a fully complete automated storage facility. I offer my sincere apology for giving a negative review from another negative review I had seen. I pride myself on honest posts. It's not fair when mistakes are made at the expanse of a business struggling to stay afloat in Seattle. You have my respect and I hope this helps. Staff and Management at this storage business is caring and responsible the kind of place you'd respect to bring your belongings for safe storage. Please forgive my short comings and review that left you with a heavy heart. Sincerely D Cool. ... Read more

I would highly recommend renting at this storage facility due to the fact that Liza (property manager) was very accommodating, friendly, and knowledgable. She was able to help us through the process even though it appeared to start off a bit rough (not her fault). I went there to rent a storage space and had one picked out. The only problem was that it was the last one in the size I wanted, and the automatic light sensor was not working. Liza assured me that it would be addressed immediately. She was communicative throughout the whole process. When it appeared that it was not going to be fixed immediately, she provided me with updates and options that worked out for both parties. I was very happy with her willingness to ensure that I left happy and continued to support even after the move in. The other pluses going for this place that make it top notch is the other staff member on hand (Shawny) were helpful and pleasant in assisting us. The property is clean and secure and well lit in the parking, storage spaces and floors. I love that the parking/loading area is covered and storage is accessible quickly via tow sets of elevators. I would definitely recommend this place to anyone looking for a long term /short term storage place. ... Read more

These amenities include Climate-Controlled, Indoor, Retail Available, Onsite Manager, Truck Rentals, Security Camera, Parking, Credit Cards Accepted, Elevators, First Floor Access, Multi-Level Storage and Online Payment. 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 West Coast Self-Storage - 3736 Rainier Avenue South can satisfy all of your storage needs. Different sizes here range from 25 to 230 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!
