This is the first time we have seen this apartment building on NLA.
(I checked twice)
The Crestmont Arms, Los Angeles [1929]

The location is just off a curve on Sunset Blvd. at 1519-1525 Griffith Park Blvd.
The building is some distance from the street so it's a bit difficult to get a good look. (the overgrown tree that has engulfed gate also hinders the view )

The gray building on the left is a gas station in the 1929 photograph.

I believe this short stretch of Griffith Park Blvd. is now closed to traffic.
