Kenwick Lodge is one of the log cabins in Kenwick Woods, near Louth. It's a detached one, so you've got space around you. You're in the middle of a few hundred acres of woodland.
It sleeps six. There are three bedrooms and two bathrooms, which makes things a bit easier. It's got a 4 Star rating, so it's well equipped and comfortable.
You can walk straight out into the woods from the cabin. The golf course is on the park, and the clubhouse with a bar and restaurant is about half a mile's walk through the trees. The park itself is quiet.
Louth is the nearest town, about a ten minute drive. It's a proper market town with a high street. There's a leisure centre there if you need it.
The coast is about twenty minutes east. Sutton-on-Sea and Mablethorpe have the long sandy beaches. If you go north up the coast for another twenty minutes or so, you get to Donna Nook for the seals. Go in the winter for the breeding season, it's something else.
As for facilities: it's all on one level, there's parking right outside, a garden area, WiFi, and TV. Bedding and towels are included. No pets, sorry.
