I have just returned from a three night stay with this wonderful couple. They didn't just host a bedroom, they welcomed you into their home in true Air B&B fashion. Everything you think you might need was provided for and if you forget something, don't worry!
The location was great with access to all areas of Dublin. The bus stops are quite literally just around the corner and G will fill any tourist gaps with a wealth of info!
I wouldn't hesitate in recommending G and D as hosts and when I next visit Dublin, I know where i'll be staying!
