Traveling a lot, we have stayed in many 5 star Airbnb's. I would give this place a 5 star after 2 improvements; the most important would be the heating.
It was very cold even with the fire; especially in the bedrooms and back of place. Ireland is cold (all year round by my standards) and many Airbnb's had either good heating or just one of those plug in heaters that was just fine.
This simple upgrade would make this place have everything you need, as the rest is all there. Comfy beds, clean enough, washer & dryer, beautiful location, nice host, kitchen, good wifi, etc.
The only other feedback is that if you are coming from Killarney area or going to, it's not 15min. as it shows on the map & in the listing, but rather 30min. May not be an issue for some; but if you have to go round trip, it's an hour & that can be an issue if you're short on time.
If cold doesn't bother you and the distance isn't an issue I'd recommend staying here. If the heating issue gets addressed; I'd also recommend staying here. Hopefully the heating will be addressed as I noticed most of the reviews here say the same thing about it.
