Robin's place was pretty much exactly as described. The house has a kind of odd layout and felt a bit like if your older aunt and uncle were letting you crash at their place for the week. :)
The house has 3 main rooms downstairs - a front sitting room, a full kitchen with table for 6, and a back "florida room" with a couch and chair and TV. The "backyard" is in a bit of disrepair and outdoor furniture could us a cleaning, but it was so hot we didn't use the main backyard. There is a nice 6 person table right next to the house (side yard, right out the sliding door) and beat up but very usable grill all of which we used frequently. There is an outdoor shower which was nice.
Upstairs there are 3 bedrooms with a comfortable bed in each. Full bath upstairs and half bath "Harry Potter Closet" downstairs. AC was great and TV served its purpose.
Kitchen is very usable and has everything you need to cook and eat. Its a bit of a hike to the beach when its hot but certainly not insurmountable. Probably 12-15 min? But is any "walk to a beach" really a problem? There is a cut through (head left out of the house and zig zag between the two lakes) so you do not need to walk on route 1 AND the house provided a beach push cart which made the walk a breeze.
The house served its purpose & was exactly as stated. Remember to bring linens, towels and toilet paper. We were 4 people total and found that to be just the right size. Robin communicated via text very quickly and answered all of our questions.
We would 100% stay here again. Thanks Robin!
