Our group of women friends has been getting together for a long summer weekend every year for almost 30 years now, so we've rented a lot of large houses!
Highs: location, location, location. The view is fantastic, the walk to access the water is quite reasonable, and the neighborhood is quiet and good for long walks. Sleeping arrangements were also pretty good for 12 adults, which can be challenging.
Not-so-highs: the kitchen on the main level (as expected) was a bit small (two cooks max at a time) and the pots, pans, dishes, etc. could use some refreshing and additions.
