Last night, Crescent Heights threw a gigantic opening party for its luxury rental property--and the city's largest--at 18 Tenth (aka NEMA). Surprisingly, not all residents are working for Twitter next door. We snapped Crescent Heights principal Bruce Menin, who flew in for the 450-person christening. He tells us (or more like shouted over blaring Al Green) that amenities are at the "bleeding edge of technology." Tenants text their allotted number to valet, and by the time they are downstairs, their car is waiting. NEMA also has keyless entry doors and a digital antenna system so smartphone-obsessed residents never drop a call. (Even party swag bags included emergency chargers.)

The 754-unit site will include four residential towers, three landscaped terraces, a 7,000 SF gym, and a heated saline pool. Residents just started moving into the two south towers in early October, with 267 of 317 units filled. While many of the residents work for the 140-character bastion, we also met some Google and Walmart.com employees. The North Tower starts preleasing in early December and opens early next year. Two-bedroom, 1,234 SF units start at $5,195 per month.
