Overall, this could be a good stay. I'll save our problems for the end. First it's a beautiful house on a very nice property. The house has lots of space for privacy...even with 11 adults. It's on "15 acres" but it's not usable except the yard. It's tucked in off the road, but there would be road noise if not for the fountain which drowns the noise.
It's hot in August (we had 101F) and the place doesn't have A/C except for the upstairs master BR which has a small unit. It was advertised that the place had fans, but I only found one (except for ceiling fans). We bought a box fan to blow the cool night air in during the night. I think most of the time, this wouldn't be an issue, but I think the place should provide more portable fans.
Our master A/C went out and the owner addressed it immediately.
The well went out and we had no water-11 people w/o showers, toilets, or washing dishes. The owner was on this right away as well and had someone coming to fix it on a Saturday. He brought 10-12 gallons of water for the toilets. He gave me his personal number and told me to contact him directly. We went paddle boarding and didn't ever hear from him. I texted and called with no response. We arrived early evening-no water, and then I heard from the management company, not him that it wasn't fixed. We hauled water from the pond to flush our toilets. He never talked to me, but sent a curt text when I expressed my frustration. Yes, we got a partial refund
