This is Silvershell View, it's a bungalow up on the hill above Port Isaac. Detached, so it's just you and the garden. The garden's got a patio and gets the sun in the morning.
It sleeps four. Two bedrooms and a bathroom, all on the same level. It's got a 4 Star rating so it's comfortable and well looked after. The stairs thing isn't an issue here.
You can walk down to the village. It's a proper Cornish fishing place, the one they use for Doc Martin. There's a shop about five minutes down the hill, and a pub a bit further. The walk back up is steep, just so you know.
You're right on the coast path here. You can walk for miles either way. By car, Tintagel is about twenty minutes. Boscastle is a bit further. Padstow is maybe half an hour, depending on the traffic. You can park there and do the Camel Trail along the estuary.
For facilities, it's got the normal things: a washing machine, dishwasher, WiFi. There's a cot and a highchair if you need them. Bedding and towels are included. Parking is right outside.
