Carol's room is the perfect foothold for visiting around: it's close to Heuston Station and Phoenix Park and just 20 mins walking to Temple Bar, but if you prefer taking the bus, there are some lines passing really close by. There are also some supermarkets just around the corner.
Her husband and Carol have been really nice and always responsive when I have any question.
If I cannot convince you more, I'll just say: cats :D
There are 2 cats living there, they are the sweetest balls of fluff going around and they are very well behaved.
