Micheál was a great host - very reactive in his answer.
The falt is ideally situated if you are interested in Temple Bar, but not only... shops, Guiness Storehouse, distilleries are situated in an area of less than 15 minutes. Nice bakery (Queens of tarts and The bakery) closed to the flat.
The flat is quite, and perfect for a family of a city trip between friends.
One last thing, the bus stop for an airport transfer is less than 200 meters.
