I never met Nina. The place had a number pad entry system. I think I was the only person in the house, although someone else may have arrived while I was sleeping. That was a bit uncomfortable.
Nina was friendly and helpful over text messaging and everything worked out fine, but I was put off by the stained carpet. The bed was ok, but not really comfortable, tended to sag a little.
All in all, it's an inexpensive way to stay close to LAX airport if you have to fly out the next day.
