M's place is in a good location if you want to enjoy some time at the beach (it's about a 15min walk to Venice Beach). There are plenty of restaurants around as well as a Whole Food market.
Communication with M was quick, friendly and very detailed.
Check-in is only flexible for an additional $20.
The place is clean but quite small, I would not recommend staying there with three people. It is in the backyard of the main house and there are curtains on all of the windows to guarantee privacy, however this makes the place quite dark and, in my opinion, not a place you want to hang out that much. This is also because it is pretty small and other than the bed and the kitchen table there is no area to sit, relax and chat. But the place is perfect for people who want to explore the city and are mainly looking for a place to sleep. Also the kitchen comes in pretty handy if you want to prepare some snacks or make coffee.
