This B&B is on the least populated and most authentic of the Aran Islands, Inis Meain. If you're travelling outside of the main tourist season expect the few shops, restaurants, and pub to close early, or not open at all. Call ahead and they may open to make you dinner. Or arrange to use the kitchen in the B&B for self-catering.
As for the B&B itself, it's great. Most rooms share bathrooms in the hall, but 2 of the rooms downstairs do have ensuite facilities. Martin stays in a cottage behind the main house so guests have access to the entire house: living and dining rooms, and the kitchen. The atmosphere is relaxed and unfussy, and breakfast was delicious and generous. I wanted to stay a week or more but only had 2 nights. I would definitely book with Martin again.
