Trevina is in Weston, on the Isle of Portland. It's a semi-detached house. Sleeps four, two bedrooms. One bathroom. It's a 3 Star place, so it's comfortable and clean, not luxury.
The garden is enclosed, which is good because we take pets, up to three. There's a dog crate, some towels and blankets for them, and an outside tap to rinse muddy paws.
You're right on Portland. The coast path is on your doorstep. A 20-minute walk gets you down to the beach at Chesil Cove. For a proper sandy beach, Weymouth is about ten minutes in the car. The sailing academy is over there at Osprey Quay.
The Jurassic Coast is the main thing here. You can drive east to Lulworth Cove and Durdle Door, or west to Abbotsbury and on towards Lyme Regis. It's all within half an hour. Weymouth has the usual seafront things, and you can get a ferry to Guernsey from there if you fancy it.
There's a shop and a pub a few minutes' walk away. The pub does food.
Inside, it has the basics: TV, wifi, washing machine, dishwasher. Bedding and towels are included. There's a cot and a highchair if you need them. Parking for one car on the drive.
