I spent a week here with my wife, her siblings, her mother and everyone's children. There were 10 of us in total. The house is large and easily had room for everyone. The layout is great in that the bedrooms are towards the front of the house in case little ones need to go to sleep early. The kitchen, dinning room and living room all connect which allowed for everyone to feel connected during the day. There is also ample outdoor space. There are many restaurants in the area and a couple of nice parks/playgrounds.
There were a couple of maintenance/cleaning issues when we arrived, but our host promptly took care of them.
For large groups, I think this place provides a great opportunity to all stay under the same roof and not feel like you're cramped or don't have enough space. Also, with little ones, it's hard to stay outside too long and the A/C in this house was great. Our kids had space to play and stay cool when we need a break from the heat.
