Stayed here in July 2016 on a weeks visit to the Trossachs with my wife and 2 kids. The gate lodge is situated on the outskirts of Aberfoyle up a private road, very peaceful location situated up in a forested area.
You won't get a mobile phone signal in the lodge but frankly that's not a bad thing and you will get one just down the road closer to Aberfoyle itself, there is free wi-fi in the lodge so it's easy to keep in touch and plan trips without being disturbed. The lodge is clean, well presented and well equipped with appliances including a dishwasher and washing machine the only things we missed were a freezer compartment and a microwave not a big deal though just buy your ice creams when you are out ;-)
The cottage is pet friendly and garden area at the back was enough to keep the kids amused when we weren't out and about, actually found frogs and newts in the pond which impressed the youngsters greatly.
If you are looking for a peaceful getaway in the Trossachs I'd recommend it..
