I own at Briarwood, too. We were there last summer and again last month. The summer unit (the one we own) had not been updated recently, but it was certainly quite clean and comfortable. Also very large, a large 2br townhouse with a full, well-stocked eat-in kitchen and a small private yard behind the townhouse, with a grill and a picnic table.
The unit we stayed in during President's week had been updated and, again, it was very clean and well maintained. Same layout, but new furniture, including a comfy new sectional. The master bedroom was not a loft in either of the units we saw, so I'm not sure where that might have been--I thought all the 2brs were identical. Maybe the 3brs are different.
Briarwood is not right on the beach but it an easy drive to six or seven nice ones, plus a lake beach. We passed Southcape and thought those looked good from the outside, too. Briarwood is not easy to get in the summer--nothing on the Cape is that easy to get in the summer, especially a 2br.
