Linda the on-site manager provided excellent customer service when we needed to move to a larger storage unit. She provided several options and found the unit that satisfied our needs. She quickly completed all the paperwork and had us in a bigger unit without any hassles. Thank you! ... Read more

Single struggling disabled pregnant mom with two toddlers and no help. This place needs me to clear all 3 units out by today and I have no help at 27 weeks pregnant. Time to push myself thanks to this place. Discriminating place against single struggling pregnant moms with kids. Don’t rent here. Wow customer experience from Lena! Lena was outstanding in her professional knowledge as well as very friendly and helpful. She assisted my two toddlers and I as well as our service dogs. Always has a smile on her face and is very friendly and respectful! She is very prompt to respond and was quick to notify and assist me when I could not figure out the locking system for my unit I’m renting. She was also very understanding and patient, since my life is so wild with having to move alone with two toddlers. The location she manages in MLT is very clean, my unit actually HAS light! Which is a huge plus when I’m here late and it’s never scary knowing that it’s a secure location. Thank you for hiring Lena, wonderful choice and a win employee for Public Storage! Highly recommended! ... Read more

This particular storage facility provides self storage units of different sizes, ranging from 25 to 300 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 Public Storage - 21818 66th Avenue West start from $53 and can go up to $508 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.
