We booked this trip for our family vacation which included my grandparents (85 yo), My wife and children (6/8), my sister and brother in law, and my brother and sister-in-law. We stayed for 7 days and it was a perfect spot for us. The main floor master was perfect for my elderly grandparents, while the other rooms between the walk out basement and 2nd story were well spread out to accommodate plenty of people without feeling crowded. The location was perfectly centered on everything we wanted to do, whether it was go to Portland, go to the beach, or hit some quaint Maine towns for shopping and a local experience.
The house had everything you could possibly think to include for a large family vacation, and the kitchen was excellent to cook in for 10 people, with everything we needed.
