The Fitzwilliam offers well-designed rooms in warm colors, with a lot of attention given to details (bathrobes, nightly turndown service with chocolates, etc.). Bathrooms are top notch, likewise the electronic appliances - LED TV, Internet radio and free WIreless access.
The hotel also contains two of Dublin's top restaurants, although they are quite expensive. Breakfast is affordable and offers plenty of choices.
The location right at St. Stephens Green is ideal for shopping on Grafton Street, and dozens of excellent dining and entertainment options in walking distance. Despite the location the hotel is very quiet, as most rooms face the courtyard.
One warning: The room sizes can vary quite considerably, so better to invest extra for the Executive rooms.
