I had a great stay in Mira and Ryans Garden room. I stayed there for 3 great weeks. The room is very private, and perfect if you have to work, you're travelling for a long period, and prefer to kook your own meals, or you just prefer privacy.
Everything was as described on Airbnb. The area is perfect. Close to the Beach, and 3th street. In The direct neighbourhood there are many cafes, restaurants, and shopping possiblilities. And a laundry close by.
I enjoyed my stay very much, I actually expanded it 3 times, and ender up staying 3 weeks instead of 10 days, and would stay there again when going back to Santa Monica.
I highly recommend Mira and Ryans Garden room.
