For the first edition of Curbed Miami's Rental Heatmap, we check out Miami's hottest of-the-moment rentals. Due to the recent economic Armageddon, the best digs are in Brickell, Downtown, and Midtown, where all those fancy-shmancy, amenity-laden condo towers have gone bankrupt and been converted to apartment buildings. They're new, they're huge, they're usually quite grand, and some have enough amenities to make a you gag.
