Fantastic place and wonderful host for a great value. The rooms themselves are very clean and cozy with the type of linens and bed sheets you'd normally find at a more expensive hotel. You do need to share a shower and toilet with everyone else on the floor but it's very well-maintained and beautifully-tiled The building itself is beautiful and the pub below is really great, complete with a fireplace, pool table, and craft beers. It's very easy to go downstairs, grab a pint, and sit down by the fire.
The location is ideal. You're right in the Medieval mile. Smithwicks is right up the street one direction and Saint Carris Cathedral the other. If the Pumphouse doesn't suit you there's also three other pubs right next door.
Finally, Noeleen is an extremely helpful and friendly host. When I got delayed on account of Storm Ophelia, she offered to refund me for the night I would miss without any trouble. Upon arriving, she also provided tips on all the surrounding attractions and restaurants and also told me how to get the bus to Dublin.
Overall, great place to stay, especially if you're looking for an authentic Irish experience on a budget.
