We can't recommend a stay at Catherine's highly enough. Catherine is the most wonderful host, providing great recommendations for things to do and places to see, and is so lovely to talk to.
The B&B is a few minutes drive from Clifden town itself, the views out across the bog are beautiful to look at over breakfast. And the breakfast, oh my goodness it was fantastic and set us up for the day (freshly squeezed orange juice just the best!!)
Our room was very comfortable, the bed and shower were terrific. Note that the listing we booked (and therefore the one I'm reviewing here) has a private bathroom but it's across the hallway; Catherine's other listing has an ensuite. As we were the only guests there, Catherine kindly offered us a choice of rooms, so we actually stayed in the room with the ensuite.
If I could give 6 stars I would.
