We had a really nice stay at Daraghs' place. He was very warm and welcoming and provided us with a map and a lot of suggestions on where to go for food or sightseeing. It's a reasonable walk from the flat to either the canal or trinity college/grafton street. There was a small problem with our keys, but after a quick call Daragh came over and fixed it for us. Thank you, we had a great time in Dublin!
