We loved our stay with Caroline and her husband in their home in Leixlip. They were very hospitable and helpful during our stay. She made a lovely breakfast for us for the morning that we were there, before we headed out. She was even kind enough to drop us off at the train station one morning. They had a private room with a bed big enough for two, and a private bathroom for us to use as well.
My only warning to future guests is that the taxi situation can be difficult being a bit further into the countryside. Definitely have free now app pre downloaded to be able to order taxis, but also try calling the local neighboring taxi companies. We had really good luck getting taxis to Dublin through the Dunboyne company. Or plan to rent a car to make your transportation easier.
Also, don’t sleep on the public transportation. It is very easy to figure out using google maps, and purchase a leap pass from the airport for 1, 3, or 7 days. These are way more worth it that the reloadable leap passes.
