From the double-height glass-fronted foyer to the immaculately presented rooms, this luxury city centre hotel exudes uncompromising elegance at every turn. Acid yellow, burnt orange and lime green set the tone in the guestrooms, and dark wood is cleverly incorporated to balance out the vibrant shades. Each room offers retro 'dial' phones, MP3 connections, flatscreen TVs, sunflower showers and great city views. Splurge on the Penthouse Suite and you'll also get your very own limo service and 24/7 butler. Around 90% of all materials used is of Irish origin, and the theme continues in the restaurant where all food is locally sourced to keep those airmiles down. Right beside the Grand Opera House, this downtown abode really is a cool, classy city stand-out.
