The room is Nice, its not that big but it offers everything and more a hotel does: fridge, microwave, bathroom, closets, tea, coffee, elevator etc.
Ed is a good host, replies very fast and friendly. He gave some good advice where to get coffee/drinks/food nearby.
There are some very nice cosy pubs nearby. There is a costa coffee place, some supermarkets and places to get breakfast nearby.
Public transport to the city centre was very easy. There is a tram stop at 5 minutes walking distance, it takes about 20 minutes to the centre by tram and a return trip costs €5,40 a person.
I had a good stay and a good time in Dublin. I would definately recommend this place because of the location and the price/quality ratio.
