I would like to have it as a holiday home and to rent out to others as a holiday home, but I wouldn't want to live in it personally. I don't think the house is particularly attractive. The garden isn't as close to the cliff edge as it looks. The South West coast path runs along the bottom of the garden and there is a further bit of sloping grass on the other side of the path.
What I did find interesting is that the dining table only has seats for 6 and there are 4 bedrooms - most of the other houses seat at least 8 at the dining table. I haven't been able to tell from Google maps where one would park, either. I'm assuming there is some space just off the road but not much.
Porthcothan is a bit out of the way as well, it's quite a drive to the nearest big supermarket and it looks like the only things in the village are a tiny little beach shop, a McDonald's and a pub.
