Created from four Grade A listed Georgian Houses, one being the Duke of Wellington's birthplace, this beautifully restored building boasts bright, antique-filled rooms and a modern wing overlooking a private garden. If staying here, invest in the rooms facing onto the Dáil. A two star Michelin restaurant, trompe l'oile swiming pool and two reception rooms with fantastic sofas in which to sit and enjoy a glass of wine, makes The Merrion a particularly romantic idyll.  And connoisseurs will be pleased to learn that a French vineyard makes wine exclusively for the hotel, and the extensive art collection is privately owned by one of the three owners.
