There are three showers in the 18-person dorm room, but only one that has privacy (locked compartment with extra room to hang up clothes) and that is the weaker shower. The other two are enclosed together in another compartment with a faulty lock and one of them doesn't actually work. (The other does and is the strongest shower, but pity about the broken lock.)
The staff are incredibly friendly (gave some great suggestions for what to see and where to eat), the breakfast is filling (you can eat however much you want), and the location is incredible (just a stone's throw away from Trinity College). I thought staying in a 18-person dorm room would be loud, but with headphones and eye shades I slept like a baby.
