Karol is an amazing host! This was my first time using Air B&B, and I would stay with her again in a heartbeat (already dreaming about my next trip)! She made me feel right at home, gave me advice on what to do and how to get around Galway, and was always willing to chat if we were both around. Her house is absolutely lovely and the room is perfect - I stayed for a full week and was very comfortable the whole time. They live about 20 minutes walking distance (or an easy bus ride) from the city of Galway, where you can find endless things to do. I met tons of musicians and played and sang in the pubs with them - had a total blast. When you stay at Karol's you have to go to O'Connor's pub in Salthill, right across the street from where they live. The people are extremely friendly, the atmosphere is incredible and there is great live music!
All in all, just be prepared to make great friends and have a very comfortable stay when you pick Karol's home. :)
