We had a great stay at Kim's. The accommodations (bathroom, bedroom) were *very* clean and there was a useful little kitchenette setup in the room.
Our hosts were very warm and friendly - one of our favorite things about airbnb is meeting nice people wherever we're staying, and so that's always a plus.
Except to keep quiet hours in the evening as there will be little kids asleep in the house, and also up early, which may or may not interfere with your plans to sleep in - for us it wasn't a problem at all, just something to be aware of when booking. Would definitely stay with these folks again.
