Apartment 2 is at Glebe Farm in East Barkwith. It's a ground floor flat. It sleeps two people, just the one bedroom.
The farm has a fishing lake you can use. There's some decent walks and cycle routes from the gate. The place is quiet, just fields out the window.
The village shop and the pub are about half a mile down the road. Both are fine. The pub does food.
Lincoln's about a 30 minute drive if you want a day out. The cathedral and castle are up there. Lincoln Cathedral is worth seeing. The Lincolnshire Wolds are good for driving around. Louth's a nice market town. Horncastle has a lot of antique shops if that's your thing. Market Rasen has the racecourse.
The facilities are straightforward. There's parking right outside, WiFi, a TV. Bedding and towels are included. You can have one dog. There's a BBQ you can use.
The stabling mentioned is for if you bring your own horse. You'd need to sort that out with the owner directly.
