Colm's place is perfect for exploring Dublin. We stayed at Colm's a few days and walked all over Dublin. There are many attractions just a few minutes walk away and when I needed to go farther there was always a cab available right outside the front.
Colm's place is very new and clean. Comfy beds, nice little kitchen, living room and everything we needed. Check in was very easy, and everytime I had a question Colm responded to my texts within minutes. Really nice place.
