The Merrion Day Spa is another handy one if you’re touring in the city, as it’s finely situated at the 79 Merrion Square. The spa’s most popular package consists of a skin analysis, a customised mini facial treatment, an eye mask and a head massage. The head massage can also be replaced for a hand and arm massage. You will also be able to choose between coffee, tea or hot chocolate to end your package with a final treat. This is arguably the best value day spa Dublin has to offer.
