Harebell Cottage is in Addlethorpe. It's a detached bungalow, so everything is on one level. Good for less mobile people or if you just don't want stairs. There's parking right outside.
It sleeps six, across three bedrooms. There's one bathroom with a shower. The place has a 5 Star rating, which means it's well-equipped and refurbished to a high standard. You can bring one dog.
The garden is enclosed, so it's secure. It looks out onto a big village green, which is handy if kids want to run around.
You're about a mile and a half from the coast. Ingoldmells and Chapel St Leonards are the nearest bits. The beaches are sandy and long. Skegness is a short drive south for all the classic seaside stuff: pier, amusements, that kind of thing.
There are two pubs within a mile. The shop is about half a mile away. For activities, Fantasy Island and the trampoline park are very close if that's your thing. There's local fishing and horse riding too.
The facilities are what you'd expect: wifi, washing machine, cot and highchair if needed. Bedding and towels are included.
