Sunstone Hotel Investors Inc. intends to forfeit the 258-room W San Diego to its lenders after its efforts to reach a compromise on the luxury hotel’s $65 million securitized mortgage failed.

Sunstone, a real-estate investment trust that owns 43 hotels, bought the W for $96 million in 2006 from a group led by developer Gatehouse Capital Corp. Since then, the slumping performance of the W San Diego and the broader hotel market has made supporting that mortgage a challenge for Sunstone.
