The Haven is in Hornsea, in the middle of town. It's a semi-detached house. You can walk to the shops or the beach from here.
It sleeps five. Three bedrooms, one bathroom upstairs with a bath and shower. It's a 4 Star place, so it's comfortable and well equipped. The garden is a small, enclosed courtyard out back. It gets the afternoon sun.
Inside, the main room has the kitchen, dining table and living space with a wood burner. There's a TV. The stairs are standard for a house like this. Two of the bedrooms are doubles, one has a single bed.
You can bring two dogs. Bedding and towels are included. There's a washing machine and a dishwasher. Parking is on site for one car.
The beach is about a 15 minute walk. The promenade has the usual stuff – fish and chips, an arcade. Hornsea Mere is a short walk the other way, good for a stroll or birdwatching.
Further out, within about half an hour, you've got Burton Constable Hall, Sewerby Hall in Bridlington, and the RSPB reserve at Bempton Cliffs. Hull is about a 45 minute drive for things like The Deep aquarium. Beverley is closer, maybe 25 minutes.
