Eilean Beag is just outside Corpach, near Fort William. It's a single-storey house, so no stairs, which is handy. Everything's on one level and the doorways are wide, so it's fairly straightforward if you have mobility issues.
It sleeps four. Two bedrooms, one bathroom with a shower. It's got a 3 Star rating. That means it's clean and comfortable, not luxurious. You've got your own parking space right outside.
The house is detached so you've got your own space. It's open plan inside. There's a washing machine and towels are included. The wifi usually works fine.
You're a few minutes' walk from the shore of Loch Linnhe. It's not a private beach, but you can easily get down to the water. There's a shop and a pub about five minutes away. The pub does food. A restaurant is a bit further.
Fort William is about four miles down the road. That's where you'll find the big supermarkets and most of the shops. It calls itself the Outdoor Capital, which is fair. You're right in the middle of everything.
You can see the Caledonian Canal from here. Ben Nevis is right there. For a day out, you can take the gondola up Aonach Mor, or drive over to Glencoe. The Corran ferry is close, which is the quick way to get to the Ardnamurchan peninsula. The Jacobite steam train, the Harry Potter one, runs from Fort William too.
Inverness, Loch Ness, Oban and the Isle of Skye are all possible for a day trip, but it's a good hour or more in the car to most of them.
