Herons Nest is a one-bedroom flat above the main house. It sleeps two. We've had it rated as a 4 Star, so it's comfortable. You get your own private balcony that looks out over our lake. It's a nice spot to sit with a drink.
The flat is all on one floor. The living area is open plan with big windows so you get the view. There's a decent sized double bedroom and a separate shower room.
You're on our grounds, so it's quiet here. But it's only about a ten minute walk into Bourton-on-the-Water itself. You can get to the river and the shops and pubs from there easily.
It's a good base for the Cotswolds. Stow-on-the-Wold is about ten minutes by car. Moreton-in-Marsh is fifteen. Cheltenham is roughly half an hour if you want a bigger town. Oxford is under an hour for a day trip.
You can bring one well-behaved dog. There's parking right outside the flat. Bedding and towels are included. There's a dishwasher, TV, and wifi.
Just to be clear, the lake is there for the view. There's no fishing allowed.
For planning days out, the National Trust Cotswolds page is useful, or the official Cotswolds website.
