U-Haul Moving & Storage of Doral at 8700 Northwest 77th Court, Medley, Florida.

Nice storage facility with mostly climate controlled units. Their website isn't clear on this, but any second floor units are easily accessed via large elevators! Note that they charge $10 extra monthly for after hours access which doesn't appear on the UHaul website, but is definitely worth it if you need to get in after office hours-- very few storage facilities around here have access outside of their office hours anymore! Very clean, safe, and well maintained. Hialeah Gardens police tend to be in the area overnight, so you don't run into people lurking there.

Tricky to access at times due to road construction off property, though that should clear up once the Palmetto is finally done (ha!)
