Hill Mill Cottage is in Tresham. It's a detached place converted from an old watermill. It's on a six-acre estate with a lake and some woodland, so expect to see ducks and geese. The lane outside is very quiet, just a single track with passing places. It's peaceful.
It sleeps four. Two bedrooms, one bathroom. It has a 4 Star rating, which means it's well-equipped and comfortable. It's not huge, but it's fine for four people.
There's a garden and a patio with a BBQ. The facilities are good: dishwasher, WiFi, TV. There's a games room in an outbuilding with a table tennis table. Parking is right outside.
It's a good spot for walking. The Cotswold Way is only about a mile up the lane. For a day trip, Slimbridge Wetland Centre is great if you like birds. Westonbirt Arboretum is also close, especially nice in autumn.
Shops are about two and a half miles away. The bigger towns are a bit further: Bristol, Bath, and Cheltenham are all roughly 20 miles, so about a 40-minute drive depending on traffic.
