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

These amenities include Climate-Controlled, Indoor, 24 hour access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Elevators, 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 Extra Space Storage - 340 South Myrtle Avenue can satisfy all of your storage needs. Different sizes here range from 20 to 300 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.

Storage units offered by Extra Space Storage - 340 South Myrtle Avenue come at a variety of prices, starting from $44 per month for typically smaller units. However, larger spaces can set you back up to $380 a month.

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!
