Manorbier Boat House is in the village, about a ten minute walk from the beach. It's a 1930s house, so it's got a bit of an old-fashioned feel. Timber floors, some rugs, antique furniture. It's not modern, but it's comfortable.
It sleeps five in three bedrooms. There are two bathrooms, which helps. One is on the first floor with the master bedroom. That room looks out over fields towards the castle and the cove.
French doors from the living room open onto a big decking area. There's an enclosed garden too, with a cottage garden feel. It's quiet.
The village has what you need. There's a local shop, a pub, and a cafe. A restaurant is about three minutes walk down the hill. The beach is sandy and sheltered. The castle and the Norman church are a short walk away.
You're allowed to bring two dogs. There's parking on site. Facilities include a washing machine, dishwasher, and a woodburning stove. Bedding and towels are included. There's a cot and highchair if you need them. The entrance and ground floor are wheelchair accessible.
Tenby is about a fifteen minute drive. For bigger days out, the Pembrokeshire Coast National Park is right there. The Park Authority site is good for walk ideas. You can also look at Visit Wales for the Pembrokeshire coast. St Davids is less than half an hour away by car.
