For me the perfect location for exploring central Dublin. Mary's handsome period house is nestled in Ranelagh which is really a city village, within comfortable walking distance (if you choose) or an easy Luas ride (or Buses).
The local amenities in Ranelagh are great also, a nice selection of convenience stores, pubs, cafes and restaurants on hand if you want to escape the crowds after a day of touring around. It's got the proximity and style without the crowds and heavy traffic, the perfect antidote to a hard days touring the city...
