Leeson Bridge Guesthouse
You might free up a good chunk of your travel budget by shopping at a food market in the Georgian Quarter and cooking your own meal in one of this hotel's studio room kitchens. Book an executive room for perks like a private Jacuzzi and sauna. After the full Irish breakfast you will be plenty fueled to traipse over the Grand Canal and around St. Stephen's Green. The hotel is conveniently located 30 minutes from the airport and close to public transportation.
