We had 14 including 4 small children, and had beds to spare. That said, the room layout is odd. Have to walk thru some rooms to get to an adjoining bedroom. OK for family, but possibly awkward w friends.
Nevertheless, quite comfortable. The outdoor space is perfect. Shopping is about a mile away, and quite good. One of the guys rode his bike daily and said it was perfect.
Took some great hikes, and climbed fire towers for pretty views.
Suggested activities: The FDR home for sure,and give it 3 hours. Lunch at the CIA (get a reservation). Dinner at the Flatiron in RH was excellent (also, a reservation). Nice morning with the kids picking strawberries. Everything we did was a short drive from the house.
Service and management---excellent. Had a broken toilet in mid week, and it was fixed promptly. The house is beautifully equipped and clean. High end linens. A cook's kitchen. There were condiments and spices from previous visitors, and I heartily approve---didn't have to completely re-stock the panty and fridge.
Bottom line: Expensive, but would not hesitate to return.
