Where on Sunset? Do you know the cross streets?
10100 Sunset Boulevard, in Beverly Hills.
It was torn down in November 2002. There are some lovely pics at the link.
It's in the really curvy part of Sunset Blvd just about a mile east of Brentwood but not as far as UCLA. I went to school at Marymount right close by. The house is white now.
I work in Brentwood and usually take the freeway home. Next time I take surface streets I'll look for a cross street ... but, as you know, they are far and few between.
