Stayed here for business and had a very pleasant experience. It's close to Merrion Square (about a 5 min walk).
I loved how the bedroom was right next to the window. Waking up to the sun (I got lucky this trip) was nice.
There's a SPAR convenience store across the street as well as some other eateries nearby. This place has a washer, which is nice, and there are racks in the closet to dry your clothes.
I would stay here again given the convenience.
