This is a gem! We (a couple) stayed at Irma's place for 3 nights, and it was simply wonderful! The hexagon is a one-room chalet surrounded by trees, situated in the middle of the awesome hilly green wilderness around Westport. Irma's house is next door; apart from that there are no other houses directly around the chalet, and even from the bed you have a great view of the surroundings through the panorama windows. It's the perfect place to go for nice walks in the area, to visit Westport and explore the bay, or just to stay in the chalet (or on its terrace), heat the stove, take a good book and enjoy this cosy retreat!
Our arrival went perfectly, Irma had already given us all information and instructions beforehand. We didn't have a car, so we took a taxi from Westport. If you do that, please refer to Irma's place as "Cuckoo Hexagon" or "Cuckoo's Nest", then some taxi drivers already know the way - and if they don't (as in our case), the directions given in the description on Airbnb make it easy to find. But those directions are only suitable for someone going by car - if you go by foot or by bike, then you should take another route, since the road is too dangerous (narrow, curvy, with cars and buses driving quite fast!). We found the kitchen equipped with everything you need, including all basics for cooking (salt, oil, etc.), and Irma had even prepared milk, eggs and a wonderful soda bread for us! On the day after our arrival, we got to know Irma in person (a really nice and interesting person), and she gave us a lift to Westport, showing us the quiet route from her place to town (avoiding the busy road) and giving us lots of additional hints and recommendations. Westport as well as the whole area around it is for sure one of the most beautiful spots in Ireland!
We've enjoyed our time in the Hexagon very much and can only recommend this wonderful place!
