It's a large dormitory hostel with many guests, so you have to temper your expectations. But the staff work hard to keep the place running, it has everything you need, the breakfasts are generous, and it's one of the few affordable places in Dublin. Two warnings: someone has to buzz you in each time, and though there is 24 hour staff, I did get stuck in the lobby once for 10+ minutes, because someone left their post. And I found the WiFi strangely irregular, jolting from great to dropping me entirely every few minutes. Still, the staff are patient and helpful, and it's a fine base for seeing Dublin.
