Kristin and Chris's place is the perfect spot to stay that is near LAX but also on a quiet street and close walk from the USMLE Step 2 CS testing center (for fellow med students) and a lot of convenient food. The bedroom is homey and the bed is comfy. And their dogs are very cute and friendly!
Checkin is super easy. They're a 15 minute walk from the CS testing center and Kristin is super accommodating and they make leaving your luggage there during the day very easy.
Whether the shared bathroom ends up being an issue or not depends of course on who you're sharing a bathroom with.
Would recommend bringing ear plugs though as the birds outside can be pretty enthusiastic in the morning!
