I assume you're looking at 260 Linden Blvd. (Linden Plaza), described by the real estate agent listing it as, "located in picturesque and convenient Prospect Lefferts Gardens," which is COMPLETELY UNTRUE! Different zip code (most of PLG is 11225), different police precinct (again, most of PLG is the 71st; this area is the 67th I believe). PLG ends at the north side of Clarkson Ave and goes as far east as the west side of NY Ave. The 2 train, BTW, is not express in Brooklyn, just in Manhattan.
If you like the area and the apartment, and feel you're paying a good price, fine, but do not let anyone tell you this is PLG! I guess it's a sign that PLG is really hot since real estate agents are applying the name to anything even remotely close.
