It's Glenrothay, which is in Dalfaber. That's a bit outside Aviemore village itself. It's one of a pair of cottages. You get the garden at the back, which is fenced.
It sleeps four. Two bedrooms, one bathroom. The rating is 3 Star, so it's comfortable and clean. It's straightforward. You'll find it warm.
There's a local shop and a pub you can walk to. The pub serves food.
For things to do, you're right on the edge of it all. The Cairngorms National Park is the main event. The mountains are there for walking. The ski centre is up that way too. Loch Morlich is close, you can go there for water.
Golf is nearby if you want it. There are a few courses. Aviemore itself has shops and places to eat. It's a few minutes in the car.
Inside, you've got a washing machine, WiFi, and parking right outside. Bedding and towels are included. No pets, sorry.
For planning, you might look at National Trust for Scotland Cairngorms and the VisitScotland Highlands page.
