Pretty 1950's resort-style looking campus in a nice residential area very far South in Miami.
Downtown Miami (Biscayne/Brickell) is the middle of Dade County. UM is 15 minutes south. 10 if you rip it. About 20 minutes south of South Beach. It is in what I call the last suburb before Miami starts to matter. There is a succession of "villages" leading north to Coral Gables, which with Coconut Grove is the last. South to North: Palmetto Bay, Pinecrest, South Miami, Coral Gables / Coconut Grove, Downtown (Brickell/Biscayne) and South Beach. Past South Beach is North Miami Beach, which is nice too. Then you're into Broward County.
I did my UG there and will be at the admitted student's day at the end of March, so feel free to ask me any questions.
Miami is a vulgar city with a cultural and social atmosphere that has degraded rapidly in the past few years. I've lived here for 24 years and I only applied to 1 school in the entire state. In all fairness this is a resident's opinion, but take it for what it's worth.
