We stayed at Suzanne's over the weekend with our family of four plus a couple. In addition to seeing Dublin, we also came to watch a football game at Aviva stadium. The house was an easy walk to the Luas, which goes as far as St Stephen's Green. From there, we could walk to most of the attractions, although Aviva is a bit far.
As for the house, it was perfectly equipped with toys, kid beds, and a small yard (garden). Suzanne left a generous welcome basket, which covered our breakfasts while there. Even so, there was a supermarket that was 10 minutes away by foot. We were able to park in the driveway, but did not use the car to get around Dublin.
