The Byre is an amazingly cosy little cabin with all amenities to be a perfectly good home (even hot water at the sink, quite luxurious ! ). If you're staying there in winter, I'd recommend to bring an extra blanket or two just in case (although there are loads there), but if you know how to work a wood stove, you're good to go !
We felt at home straight away and spent some quality relaxing time; silence, cute countryside and Bantry only a few minutes drive away: perfect combo. Highly recommended !
