You can't get more prime than Fifth Avenue. It's dubbed "the Gold Coast" alongside elegant Park Avenue and the slightly more laid-back, though equally well-heeled, Central Park West for a reason. The park, of course, lends it allure. But block after block of sturdily built, impeccably designed (by Rosario Candela and J. E. R. Carpenter) buildings carved into apartments with grand rooms and graceful proportions also make it a coveted address. The few apartments that are open for viewing, including those in buildings just above or below the choicest stretch running between the East 60s to the high 90s, offer open-house addicts a glimpse of life on the sunny, moneyed side of the street. After the jump, a list of places on Fifth Avenue (and the side streets branching immediately off it) to check in the days ahead. S. Jhoanna Robledo
