Julien's place is great. It's modern, stylish, and comfortable. Although the location is outside the city center, it's super easy to grab the LUAS (tram) across the street and get into town in a few minutes. As far as what other reviewers said about the neighborhood, we felt completely safe the entire time, and we were there for an entire month. There were a few times when a group of teenagers was hanging out by the building entry, but they actually held the doors open for us as we came back from the grocery store. I recommend Julien's place as a good option in Dublin.
