The building seems brand new, high-security access with room card to enter the building, the elevators, and room itself. ("Gardia"/Police station next door, but we were not bothered by noise). Well-located in Smithfield across from St Michan Church, between 2 tram stops (one within eye-distance from Church Street), near city bus stops (as well as the hop on and off tour buses), and airport shuttle stop (Usher Quay stop coming from airport, then cross the river Liffey; Arran Quay in front of "Ocean house" stop going to the airport). Only a short block from the famous Brazen Head pub, the oldest pub in Ireland and easy walking distance to Temple Bar area, Parnell Square and other tourist attractions like Dublinia and Christ Church Cathedral.
The front-desk staff was very helpful and friendly. There is also a little cafe area in the lobby to get soft drinks, snacks and coffee, but they close very early. There is, however, a bodega a few paces up the street so that was not a problem to get drinks and snacks after 5pm.
The room was on the small side but very clean and comfortable; No TV, but that did not bother us either.
I definitely recommend this place and will book there again if I ever get the chance to return to Dublin for a visit.
