The apartment is ample, specially in the living room area. The kitchen has everything that you need.
There's also two markets meters away, so it makes really easy to get supplies. :)
The apartment is also 10 / 15 minutes walk from everywhere you need to go, and has a great view of St. Patricks Cathedral.
Also, Hilary sent me tons of suggestions on what to do and was on point on every answer.
For sure consider this place on your trip to Dublin!
