It's the busy season for rentals, as we learned once again from today's rental market reports. So it's high time for us to update the Curbed Heatmap, our way of spotlighting the hottest rental buildings of the moment (inspired by our friends at Eater). Below, we've chosen a mix of new rental buildings and others that have been around for a little while but that remain notable for their architecture or pricing. Compiled this time around by Curbed intern Arabella Watters, we'll be updating the map regularly. See any vital omissions? Head for the comments or the tipline. And good luck, renters?these days, you'll probably need it.
