A large house in a wonderful location for anyone wishing to explore Kerry. 3 bathrooms (1 ensuite) and plenty of bedrooms if you're a large family or group. Wifi is good enough for one person to have a Zoom video call but you might struggle if multiple people are connected. (Mobile wifi signal is pretty good though if needed as a backup).
Mary (Helen's old school friend) was very kind and checked us in and brought wood for the fire when we arrived which was lovely. We were also able to check in early which really helped and checkout was seamless via lock-box. Helen was also super communicative and helpful during our stay.
As others have said, you pay for oil and electricity use. The upstairs stays pretty warm and feels really cozy though (some might find the downstairs a little cooler). For 11 days we spent €29.75 on electricity for 2 people with minimal use. We didn't use any oil so can't comment on that but we did buy 5 x 1kg bags of wood + 3 x 1kg of kindling for the living room fire. This cost €36 (€4.50 per bag) from the Supervalu in Waterville. So overall spent an additional €65.75 (approx €6 per day) on electricity/heating over 11 nights.
Overall, I would highly recommend staying in Helen's house and I really look forward to my next visit there!
