As a single business traveler, I tried several AirB places around the coastal side of LA, and found that Jill's place is definitely in the league of top three in my view.
Only drawback might be location. It's a bit of walk up and down to the beach. You won't have an ocean view or sand straight out from the room.
But it is just a five minutes ride by car to the beach, the room is up on a second floor where you can get a nice sea breeze coming in, no other building standing tall near by, and therefore your privacy is protected well.
Lastly but certainly not the least, Jill's hospitality is amazing.
She kindly welcomed me with a bottle of red wine, nice fresh oranges and bagels (with a cream cheese - perfect). Even I came back from a busy day, pretty flowers in the vase on a table made me feel like - I'm home.
