Not much that hasn't already been said.
Very spacious and immaculately clean cottage overlooking the sea (Coastguard Cottage) with a stunning view.
Cottage had everything you need. I could quite happily live there. It looks like no expense has been spared.
The lane is narrow, but we had no parking problem as there is the off road space available for number 4. I'd just suggest that if you have the option of bringing a large or smaller car, think small to make things easier.
Location wise, there's the view and it's great for walkers. The Sun Inn was only a couple of minutes drive away. We had a good meal there, and the staff were very nice.
Regarding accessibility to the rest of the island, you'll find that all points are an easy, and generally pleasant, drive away, so don't worry about that.
Would 100% recommend.
