If you're traveling around Dublin and Ireland and need a place to call home over that time, you'd be hard-pressed to find one better than at Mary's. To begin with, her lines of communication on what to expect, how to get to her place, and items of interest are fabulous. I had little difficulty arranging the stay and finding my way there. The place itself was clean and tidy, linens were prepared and ready, and provision for electronics/internet available. The place itself is situated ideally in the suburb of Ranelagh, about 10 minutes from the Dublin city centre by tram. Stops for public transport (trams/buses) are about 2-5 minutes walk away, heading into Dublin as well as further out to the suburbs. There is a car hire place within easy walking distance (15 minutes for Hertz). Ranelagh itself is a delightful suburb, with shops, supermarkets, and restaurants aplenty. You won't lack for food choices that's for sure.
As for the host herself, Mary is as friendly and knowledgeable a person as you're ever likely to find. She made me feel right at home. It can always be a little intimidating coming into a strangers home, but Mary immediately makes you feel comfortable and welcome. I can most assuredly say that if I'm ever coming to Dublin/Ireland again, Mary will be the first person I look up and I strongly suggest you do the same!
