I wouldn't normally rate anything 5 stars, but this cottage is fantastic. If I owned it, I would not let holiday makers rent it.
If I have to find a criticism it is only that there is nowhere to sit outside and have a BBQ. But that is minor.
As for location, 200m up the road is a corner shop that sell everything. 15 mins along the lochside is a pub where you can stare at the hills. Round the back and up the hill is a great walk along the disused railway line. JUat under an hour you can drive ti Stirling.
