I have had nothing short of a wonderful experience with all of the staff at this location. The facilities are always clean and well maintained. I've been a customer for 2, going on 3 years now and have always been very happy. I recently was able to downsize my unit and the process was beyond smooth. I can't say enough about the staff. One day I was looking for something in my unit and one of the staff members was driving by and offered me a water because it was hot out. They go above and beyond. Absolutely wonderful staff. ...

Extra Space is awesome! The staff are always courteous and helpful. Jessica went above & beyond to assist me with my storage search and needs, and she gets the highest rating. I left four stars because the bathroom wasn't working and the punch OUT box wasn't either, which feels like a safety issue. Overall, this place is GREAT! ... Read more

Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

This particular storage facility provides self storage units of different sizes, ranging from 25 to 450 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 Extra Space Storage - 775 South Mills Avenue start from $57 and can go up to $590 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.
