We rented this cottage with friends and it was easily spacious for our two-family group of 9 (including a baby in a cot, which the hostess provided). The house is prettier in person than in the listed photos. The garden is very large and all of our children had a wonderful time playing in it. Inside, the house is well set up for families with children, with toys, lots of comfortable sofas, and a well-equipped kitchen. There are plenty of bathrooms for a large group, and a utility room with washer/dryer, all of which we appreciated. Our hostess Tricia was quite friendly and responsive to our requests.
It is worth noting that one of the twin beds in this house is in an alcove just off of the largest lounge, not in a separate bedroom. There is another twin bed in a bedroom upstairs, a full bed in a bedroom, and two kind-sized beds in en-suite bedrooms. Because one child was sleeping near that lounge, it meant we couldn't use it in the evenings. This was not a big problem for us, however, because there was another lounge at the other end of the house where the grown ups could chat after the kids were in bed.
We had a wonderful stay at this picture perfect thatched cottage in Cookham. I would throughly recommend staying here if you're looking for somewhere in Cookham.
Our host, Trisha went above and beyond to ensure our stay was enjoyable and also really comfortable.
My friends and I have plans afoot to come back again in the summer of next year so we can have barbecues, and make the most of the beautiful sprawling garden.
