I assume that this is what is already listed as aloft San Francisco Airport. Here's some detail about the three hotels to be built on 8 acres at 401 E. Millbrae Ave, Millbrae, CA:
aloft -- 167 rooms
element -- 124 rooms
unknown -- 120 rooms
Completion by Fall 2008.
Land is now owned by Starwood Hotels. (And this makes me even more curious about the unnamed third hotel for this site.) This is directly next to the Westin SFO.
