We had a really special time at Katherine and Mike's farmhouse. Other reviewers are right -- it's old, but for us that was actually nicer than some sleek new construction. It really feels like the old Cape here, and it's neat to be in a place with such history. Having the large private grounds is very nice. The pond is, of course, ideal. We swam constantly.
Katherine and Mike couldn't have been friendlier, responding to all our various needs and questions quickly, and going out of their way to ensure we were comfortable.
There are only a few drawbacks worth knowing about, all manageable in our experience: The kitchen is pretty tight for a large group, esp. one that cooks a lot. Since we cooked outside often it wasn't a huge deal. (They've recently renovated it, so it's quite a nice kitchen -- just small.) The bedroom layout might be awkward for some groups, since the two biggest rooms are connected. It's no problem if you all know each other well. Finally, the stairs are a bit narrow and steep, which could be an issue for elderly people or young kids, but we just put up a gate and we were fine. In all, these are fairly minor issues, expected in an older house, and nothing that outweighed the pleasure we got from it. They're the only reason we didn't give it 5 stars.
Anyway it's a truly special place run by lovely, warm people in a perfect environment. We definitely hope to return.
