Great place, clean and new, wifi, the room looked like a hotel room. He even had towels for us.
It's not in the center but it's not too far and there's a city bike station right behind the apartment where you can hire bikes.
There's a supermarket 2 minutes away and you can use the kitchen (you'll need it, food in dublin is not the best...).
Cool guy, recommend his place.
