I had a lovely stay at Martha's place. The space is just as described and there is enough space so that you can have your own privacy, if you'd like to do so. Martha also leaves complimentary bottles of water and towels for guests which was very kind.
The neighbourhood is also very safe with lots of restaurant options around.
Martha is a wonderful host and I really enjoyed speaking with her whilst in LA. Certainly the best airbnb experience that I've had so far!
