I recently stayed in David's place for 2 nights. David really is a super host - he was very helpful through my stay, it was very easy to communicate and he even made me tea and toast! He is such a lovely and genuine person, also a local, so he can give you some guidance/advices if needed.
His place is very cosy and only 10 mins drive from Killarney, also it has everything you need- comfy bed, complimentary toiletries, hairdryer, Wi-Fi, parking, even a choice of snacks for breakfast- juices, yogurt, cereal, tea/coffee. Its an absolute bargain and I highly recommend it to other travellers.
I really enjoyed my stay and I would most definitely consider to stay here again when visiting Killarney next.
