My friend and I needed a place to stay for the Ring of Kerry cycle, came across Niki and Dave's place - and we're very glad we did!
It's not really a tiny house: the cabin itself is very spacious indeed, with room to sleep three in great comfort (perfect for a family of four with younger kids). Its spaciousness is made possible by the fact that the main bathroom and kitchen are located maybe ten metres away, in a separate building. This has two benefits: you get a much bigger living/lounging area and you also get a fully- loaded kitchen and more than adequate bathroom. The living/bed room has a quasi-en-suite toilet for the 3am trips, so no issue there.
Everything was spotless, everything you'd hope for was present and correct (apart from a TV signal, oddly, but no big deal). Niki's communication was friendly, clear, accurate and very timely. Everything worked. Overall, an excellent and clearly recommendable experience!
