Read some helpful reviews of Extra Space Storage at 340 South Myrtle Avenue, shared by real renters with genuine experiences and honest opinions.

I went in to this location thinking I reserved for this address come to find out I was at the wrong location and even though I did not want to go any further. A receptionist name Mary saved me for going any further. She helped me with a unit they had available even though they didn’t have my original size she gave me a bigger one informed me it was going to be more but it was fine with me. She made me feel comfortable with getting a unit and she understood that I had the wrong location. I loved that she reassured me that I was fine with renting from them. She had a wonderful attitude and very helpful. There is a man that work with her and they both have wonderful attitudes m. I recommend this location and I will be back if needed in the future!! Thank you Mary for your kindness really appreciate you!! ... Read more

This particular storage facility provides self storage units of different sizes, ranging from 20 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 Extra Space Storage - 340 South Myrtle Avenue start from $44 and can go up to $380 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.
