Loch Rusky is in Aberfoyle. It's not actually at Loch Rusky, it's an apartment in the village. It's one of three in a converted guest house.
It's for two people. One bedroom, one bathroom. It's new, so it's clean and in good order. The living area is open-plan with a kitchen. There's an electric stove that looks like a wood burner. The main gardens are shared with the other apartments, but you can sit out there.
You can walk into the centre of Aberfoyle in a couple of minutes. There are shops, a couple of places to eat, and a pub. The Scottish Wool Centre is worth a look if you're passing. You can hire bikes nearby too.
You're right in the Loch Lomond and The Trossachs National Park. The scenery is good walking country. Loch Lomond is about a 15-minute drive, maybe 20 if the roads are busy.
Inside, it's all on the ground floor. It's set up for wheelchair access at the entrance. It's got a 4 Star rating. There's a washing machine, dishwasher, TV, and parking. All bedding and towels are included.
