Main cottage housed my oldest son's wife and family of 4, ages 8,6,3.2 comfortably upstairs, my wife and I in the comfortable king room downstairs, and my 26 year old son in a separate room with his own shower - plenty of space.
The middle cottage was perfect for my daughter and her husband, and their three children ages 4, 2, and 4 months. The smallest cottage held my other son, his wife and daughter of 2 very very well. Everyone had their own space and we gathered in the yard for evening meals and family fires.
Great place, very responsive hosts and wonderful location.
Highly recommend it!
