Akiko's place is about as great an AirBNB as you can imagine. It is clean, friendly, and relatively close to the beach.
Akiko herself is a wonderful host, always has treats and various food items out (try the peaches from her backyard peach tree, which are awesome)
She is an incredibly communicative host, and check in was a breeze.
If you visiting Santa Monica, you can't go wrong staying here. Highly recommend.
