This is actually the range where I took my first gun safety class. 3 years, 8 guns, and more money than I want to think about later I still use them as my primary shooting range. All the guys that work there are knowledgable and helpful.
As for the range itself, it's by far the cleanest and most modern in the city. The lanes are all electronic and it's carpetted. As long as you are a competent and safe shooter they'll let you do pretty much whatever you want as long as you can do it safely (rapid firing, automatic weapons, etc). They'll let you shoot any rifle caliber up to but not including .50BMG which is where they draw the line (they are the only range in the city that lets you shoot rifle ammunition that I know of.) They jokingly state "If you can get it up the stairs, you can shoot it."
I've found their prices to be reasonable and have not been able to find better deals on guns online once I took into account the cost of shipping and their transfer fee and the risk associated with such a deal.
They currently offer classes for NRA Gun Safety, Florida CCW, Act 235, and I believe they will soon be able to give NRA Certifications as one of the owners is getting his certification to do that.
They are located at 831 Elsworth St. near Geno's & Pat's Steaks.
