We'd a nice stay in Sophie's for a few nights recently. The cottage itself is ideal for a couple, has all the basics you'd need. The surrounding forest is fab and definitely check out the Faerie Walk, it's very thoughtfully done.
It's about 45 mins from Killarney, 25 from Kenmare. The laneway the cottage is on is about 15 minutes of these journeys, take your time on the road!
