I had a fantastic stay at Paul & Blancas flat. The room has a good size, and the private bathroom is awesome. Loved it!
I only met Paul twice, even though I stayed there for an entire week, which means it is very private.
Sometimes, it was a little noisy early in the morning, but that didn't bother me since I got up early, too.
Public transportation is very close and I felt safe walking around the surroundings on my own even at night.
All in all I can definately recommend staying with Paul & Blanca and would stay there again, when I am in LA ever again.
