I would echo the other reviewers - a truly great find. Deirdre was an excellent host, fully deserving of the superhost status. She was very prompt in communicating, great suggestions for activities and lots of lovely touches during our stay.
The house itself is fabulous. We were lucky enough with the weather during our stay, but we would have been quite happy in the house if it had rained all week. Sometimes on Airbnb the rooms look a little worse than the photos, but for this house they barely do them justice. The kitchen is very well equipped (not just the essentials mentioned above), so no worries on that front if you want to do some self-catering. The whole house was absolutely spotless too, which is always welcome.
The village makes a great base for exploring Galway and Mayo. It isn't overly touristy, but there are good food options and shops available. The cottage isn't too far from the village either - the website says 10 minutes, but you could probably do it in 5 if you didn't stop to pick the blackberries.
Highly recommended.
