My wife and I spent a long weekend in Dublin, along with a pair of our friends. On the upside, Senan was a caring host, helpful and responded quickly to our questions, even though we never met him in person. The house, in a really quiet, nice neighbourhood, is ideal to accommodate up to four people, or a similar-sized family. Another plus is the fireplace on the ground floor, especially given the Irish weather.
A big downside was the state of the apartment itself: One quickly sees upon arrival the house has worn out and would require a couple fixes (like taps in bathroom) to get back into shape. What was most disappointing was that the house was far from being cleaned properly (hair in the bathtub, dirty carpet).
All in all, a three-star experience (at most), kind of like an (overrated) three-star hotel in a southern European country.
