Great spot in the middle of it all. We walked everywhere - to museums, the Abbey theater, restaurants, Temple Bar, and the Liffey River. We parked in the Irish Life parking garage (Car park). That was a little pricy, but not terrible. The pub across the street (The Celt) was great. Many coffee shops around.
Things to know: The rooms are all in a "mini complex" that feels like your own secret compound in an internal courtyard. If you have little kids, you may want to know that not all the rooms are connected by internal hallways but you have to go outside. If you need to have a stroller etc. this place is probably going to be tricky (lots of stairs).
We had a great time, and the beds were comfy. The rooms were warm and to cool them down we simply opened windows and doors. I can see a group of friends having a great time here. We stayed with another family and it was great to have a common area (kitchen) and private rooms as well. Bathrooms and showers worked gret.
