The owner of downtown San Diego’s W hotel has quietly rebranded the property as a Marriott Renaissance, following a change in management.

Without a formal announcement, owner Rockpoint Group of Boston has switched from Starwood Hotels’ W brand – essentially a hipper, boutique-style version of that company’s Westin brand – to Marriott’s upscale Renaissance banner.

The 258-room property at 421 West B Street is now listed as Renaissance San Diego Downtown on the website of its new management company, Connecticut-based HEI Hotels & Resorts.

An early December posting on the Starwood website said W San Diego would be leaving the Starwood system on Dec. 15, and that reservations for dates on or after Dec. 15 “will not be eligible for Starwood Preferred Guest membership benefits, award redemption or accrual.”

According to published reports, the changeover was tied primarily to the expiration of a prior management contract and was not connected to Marriott International’s recent announcement that it plans to acquire Starwood Hotels & Resorts Worldwide.

The W was the only hotel with that branding in San Diego County, and the changeover leaves just three W hotels in California – located in Hollywood, Beverly Hills and San Francisco.

The West B Street hotel opened in 2002 and was acquired in 2011 by Rockpoint Group for $56 million. Rockpoint acquired the property out of a foreclosure proceeding, after prior owner Sunstone Hotel Investors stopped making payments in 2009 on a loan stemming from its earlier $96 million purchase of the property during a market pricing boom.
