Very, very central. Easy walk to everything, bars, shops, museums etc.
Nice and clean, has everything you need, and a Tesco express round the corner if you forget anything.
As noted by others, central location also means you can hear other revellers at night. Also, as noted by others, time your showers for everyone in the group to get a hot shower. But if that’s important, go to a hotel!
Overall great place to see Dublin from, would book again.
