"I arrived at about 8:45 AM and was able to check-in as soon as I arrived! Completely changed my day as I was able to get settled before heading out for my Cliffs of Moher tour. This was not a perk I was able to get at other properties I stayed at in Ireland, so it truly made a huge difference and was much appreciated. The staff was so welcoming and I felt very safe and comfortable in the common areas. The breakfast was great and the coffee was delicious. If I'm ever lucky enough to return to Galway, I will be returning to The Ardilaun!!"
"Excellent accommodation and spectacular views. Clean and comfortable with quick access to Galway. Don’t forget to check out Salthill area as there are some nice places to eat and great pub. "
"I have stayed in this lovely hostel on and off since it first opened years ago. In fact, I used to enjoy having the female dorm to myself in the beginning until it was well known. Always a great, warm, friendly experience and very fond memories of the staff back then. It still remains the same and I enjoyed a one night stay here before heading on to Connemara. Best wishes to all the staff for a very happy Christmas and New Year 2026! Looking forward to visiting again at some stage in 2026. "
