My fiancee and I stayed at "Captain's Quarters" (CQ) for four days over the summer and had an amazing experience. The CQ is the most charming and comfortable space I have ever stayed. The photos on Airbnb do not do the space justice.
Airbnb also fails to advertise how fantastic the hosts (Henny and Tom) are. Henny provided detailed suggestions and information that helped plan the unique aspects of our visit. Tom gave us a farm tour and literally filled our arms with fresh produce while explaining their processes. All in addition to the smoked salmon and veggies laid out for our arrival.
The CQ is central to the island's many attractions and is easy to find. Expect to find the space exactly as advertised. The kitchen is extremely well equipped (coffee maker, kettle, toaster microwave and coffee grinder, in addition to standard appliances) and there is more seating and lounging room than you would expect. The bathroom and bathing area were clean and well maintained (with plenty of extra towels!).
I cannot recommend this space enough!
