I have stayed here before for the same purpose, harvested a buck once.
Like the pellet stove, and the new heating system.
I stayed upstairs and the heat was slow to rise, i would recommend turning power to the baseboard heater upstairs.
I love the location and the overall accommodation, i have been coming to the door since 1968 as a young lad, my father was a scuba diver on the wrecks, eventually buying a home on port a moor drive.
