We stayed at Kathryn's home in Galway City for three nights, as we used Galway as a home base to explore the surrounding counties. We found the house easily and as Kathryn was out of town, her daughter Debbie greeted us and immediately gave us a ton of tips and made dinner reservations for us that evening at Ard Bia (which we would highly recommend). The house is pretty ideally situated walking distance from the prom, and we also walked into town a few times, which takes about 20 minutes and saves you from having to look for parking. (One night we took a taxi back, which was under 10 euros.)
Our room was perfectly clean and though there were other guests, we also had our own bathroom. As was our experience all over Ireland, it gets fairly cold at night and there was no heating, so bring warm pajamas! (Once under the covers, we were fine, and the bed was really comfortable.) Importantly, the windows have blinds and shades, which helped keep the sun out in the wee hours of the morning. Debbie laid out breakfast for us each morning, which consisted of tea, coffee, juice, bagels and cream cheese, scones and jam, and eggs that we could cook however we wanted.
All in all, we would definitely recommend staying at Kathryn's home and we personally hope we have the chance to come back!
