I was in Dublin for a week and a half with my mom. We thoroughly enjoyed our stay here. The apartment is conveniently located - a few minutes' walk to several bus routes - and is exactly as pictured in the ad. It was comfortable - lots of space, comfy beds, no issue with heating. Also, Cormac thoughtfully stocked up on coffee, tea, milk, fruit, etc. - even Guinness in the fridge and fresh flowers on the table!
All in all, we found Cormac to be an extremely considerate and helpful host. He accommodated an early check-in (our flight got in quite early) and sat with us over tea to give tips on things to see and do. He was responsive prior to and throughout our trip. He even checked in to ensure we knew about Hurricane Ophelia being on its way.
I'd happily stay here again if I had the chance and highly recommend it.
