We had a great time staying in the Hermitage, the place is absolutely wonderful! It's exactly as described and shown in the pictures and Colm is a very obliging and friendly host - the welcome we received was just fantastic. We didn't have any issues staying there, except that it's made us not want to go home anymore.
For anyone considering to go in winter, the oven gets the cottage really rather warm if you fire it up nicely, but some warm clothes and socks definitely won't hurt either. In any case, we loved it there.
