We had an absolutely wonderful experience staying at Ronan and Edel's place while we were in Ireland for a few days. The space was very welcoming, clean, and homey and had everything we needed! I can't decide if my favorite thing was the giant, comfy beanbag chair in the living room or the lovely skylights over the bed which were particularly cool during the rain we had during our trip.
Separate from their space we did have some hiccups trying to catch the bus from the nearby stops because it didn't seem to be running when we tried to use it, but it's an easy taxi ride or fairly short walk down to the Dalkey dart station to get into Dublin center. We also utilized the Aircoach bus from the castle hotel at the top of the hill to get to and from the airport and that was the most affordable and easy option.
We would definitely stay at Ronan and Edel's place again because it was such a nice oasis to return to!
