Had my car in here for less than a month, I set up several mouse traps. I would come by every 2 days to check on it, and always had a LEAST one dead mouse, sometimes 2. The structure is not very tightly sealed, there are openings of daylight in little walls between the garage doors. I tried sealing them with some aluminum duct tape, but they still get in some how. Also, after a major rainstorm last week, the cover on my car was all wet! So there is water coming in from the roof. Not good. So for now, I just brought my car back to my house. Thank god the first month was free! I would have been bitter if I had paid 150 bucks, to have water leaking in and non-stop mouse traffic. ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that Extra Space Storage - 688 Sullivan Avenue South has to offer. These amenities include Indoor, Drive-Up Access, Retail Available, Contactless Renting, Unstaffed Location, Parking, Online Payment and RV Storage. 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 - 688 Sullivan Avenue South can satisfy all of your storage needs. Different sizes here range from 50 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 - 688 Sullivan Avenue South come at a variety of prices, starting from $41 per month for typically smaller units. However, larger spaces can set you back up to $256 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!
