Sunstone purchased the W San Diego in June 2006 for $96 million from developers including Starwood Hotels, Gatehouse Capital and Multi-Employer Development Partners. The hotel carries a $65 million, fixed-rate commercial mortgage-backed securities loan with a 6.14 percent interest rate, which comes due Jan. 1, 2018. The mortgage principal translates to more than $250,000 in debt per room.
Sounds from that quote like Starwood at least owned a piece of it.
