The condo has a bedroom with king bed. You can hear the cars go by on PCH. The other bed is a day bed in the living room. One adult or a child can sleep on it.
I stayed with my two daughters and that's plenty. The condo is a good size for three people not four.
The floors were very dusty and the host suggested to mop the floor. There was construction going on in the above unit for two days. We woke up to hammer and drill for two mornings. The water was shut off from 10am to 4pm one day during our stay. None of this was communicated to us prior to our stay or upon arrival.
