John's place is a lovely little cottage on the Sheep's Head peninsula with everything you could want in a homebase for tours around the countryside, including a small fireplace for a relaxing evening after returning from your trip.
It's just a short walk down to the seaside where you have your pick of hiking/walking tours on the Sheep's Head Trail – along the sea, up the hills, through the fields, whatever strikes your fancy (and with ~90km length in total enough to last you a few days). The next town's about 15 minutes on foot (Kilcrohane) and has a pub, a cafe/restaurant as well as a small shop, so if you've forgotten to bring something you can still stock up.
John himself is as friendly as anyone we've met over there and was always quick to answer our questions and give recommendations. So if you're looking for some peace, quiet and clean air all around you, this is definitely a place for you – we know we'll be back in the future!
