Great flat to use as a base for Dublin. Within close walking distance of Guiness and the City but also very close to the Tram service which gets you all around Dublin - you can buy your travel card from the supermarket a few yards away. Great restaurant downstairs, ideal for Breakfast (although you may need to book, it gets busy).
The Dublin Express for the airport stops about 150m away.
The flat is plenty large enough for 2 and has all you need for your short stay. No shortage of cupboard space if you wish to empty your travel bag. Kitchen seems to have everything you might need if you plan to eat in.
A great place to stay.
