I am in Dublin often, and the location really couldn't be better. Although you are so close to the action of Temple Bar, the bedroom is extremely quiet for sleeping. The only sound I heard in the bedroom was of seagulls calling.
When I arrived (an hour earlier than check-in), I was able to get right in the unit. Viny had a carton of milk and a container of soup in the fridge for me. Very nice! Washer/dryer works well. There is a switch in the bedroom to turn on the hot water. Although the pictures show a TV on a side table, there is no TV in the unit.
I will certainly see if the place is available on my next Dublin visit.
