Totally recommend.
Location was amazing - walking distance to everything. The staff had amazing communication and knowledge about the hostel and Dublin. One of my tours were cancelled and yet I was able to book another one the day before, because of all the information pamphlets they have in the common area. Wifi was fast, rooms were perfect.
Only concerns was the sudden lack of cutlery on my second last day, and the heater that none of us were able to figure out. Besides those *very* minor issues, I had an amazing time. I met such amazing people. Would totally recomment.
