We had an amazing time at Aille River Hostel. It is by far the best hostel I have ever stayed in! Great location to the Cliffs of Moher, and Aran Islands Ferry.
If you are visiting Doolin, you must stay here. The room was clean and bathrooms were spotless. Beds were comfortable and the atmosphere at the hostel is second to none. Staff were very friendly and helpful. Breakfast was delicious and cost only 1.5 euro.
