Design-led hostel/hotel hybrid in Smithfield, a cobbled square 10 minutes from O’Connell Street. Industrial-chic interiors — exposed brick, Edison bulbs — plus dorm beds, private rooms, and a busy ground-floor café/bar.

Pro tip: the Smithfield horse fair still happens on the cobbles outside the hotel on the first Sunday of every month — a centuries-old tradition that’s worth waking early for.
