Raymond is a good host: he replies you almost immediately. I also like the easy check-in/check-out: basically you just take the key from the lock yourself (with password provided after you get a confirmation)! Raymond is there too in case you have questions.
For the room, it is very quiet because it is facing the backyard; The bed is very comfy and you can sleep very well. Also it is clean (which is most important!).
The only thing that could be improved may be the shower: the water force is not strong enough for a relaxing shower. Anyway, it is not a big issue.
I didn't see the other roommate and Raymond will give you space, which is good as you may be busying running around.
The neighborhood is below Downtown area. There are factories around and so it could be quite quiet at night. If you take Uber/lyft after party/concert, it is no problem; if you walk at night, you may be the only person in the whole street. Anyway, maybe this is a thing in LA where everyone drives? haha!
Overall, it is a good stay! I would recommend to everyone if you want quick access/walking distance from concerts/exhibition in Downtown.
