We spent a weekend in Barbara and Glenn's boathouse and it was just wonderful. So close to the city and yet we felt millions of miles from the rush and noise. There are no cars on Dangar Island and on this side of the island (away from Brooklyn) there was a stillness and peace you would have to otherwise go a very long way to experience.
The cottage was exactly as the pictures show. It was as if we were IN the view rather than looking at it. The water lapped at the shore just below us, stars reflected off the water, fish flopped and night birds called. The cottage is very well equipped. We forgot the filters for our coffee maker but had a choice of 2 others. There were 2 teapots, large and small, a perfect board for our cheese plate, a variety of cups, glasses, utensils. No tv (good!) but there is a bluetooth speaker, which my phone wouldn't hook up with but we found (of course!) an aux cord in the draw beneath so we listened to some music while we cooked on the excellent stove and drank the very nice Australian shiraz (which btw is fron naked wines and has already gone into my next dozen). There was good 4G wifi, and although Barbara told me it can be intermittent we had no problems.
Highly recommended.
