This was a great stay in a wonderful location. Easy to get to everything (Trinity College, shops/restaurants, the river, Temple Bar, bus tour meeting locations, etc.)
They have lockers in the main lobby you can rent through a machine and the front desk person gave me change for a bill so I had coins to put in the machine - this was SO helpful as even after I checked out I was able to keep my stuff in the locker while walking around Dublin. I came back to get my bags before leaving for the airport.
I stayed in a female 6 bed room and it was fine - one bathroom for 6 girls goes about as far as you'd expect - especially when they're getting ready for a night out. Make friends, lol!
The bathroom floor got soaked everytime the shower was used and the bathroom is very tiny - I imagine a larger person might have trouble in there.
My one qualm was that the website says they have nightly pub crawl tours and I asked the front desk about this, they said they don't do them. So that was disappointing. I went out to Temple Bar with a girl I'd met on a day trip that day instead, which was amazing, but if I hadn't met her I wouldn't have had evening plans anymore which sucked. I was hoping to make friends on the hostel's pub crawl. They need to update their site.
