Convenient!
The Custom Hotel's location is perfect for people wanting to be near LAX. It is near LMU, so it has a lot to do around it also. The staff was young and a bit green. The valet seemed a little out of it, and the shuttle service from the airport is not super reliable. I recommend calling far ahead of when you want them to pick you up, because even with the email I sent them to remind them the day before, I ended up taking a cab. I called, waiting 10 minutes and called back to make sure I was in the right place. They said the shuttle hadn't even left yet, so I got frustrated and grabbed a cab. 
If you are planning to do some work, definitely upgrade to the business level. There is no desk, so you end up having to spread out on the bed. Not ideal for business. Also, there are no drawers, so it would be a bit difficult for a longer stay.
