Edna's downtown apartment was excellent. I stayed with a friend, and we each had our own bathroom. The kitchen is appointed with all you need for basic cooking, and the layout of the place is great.
Overall, the location is tough to beat. A 10min will get you to Temple Bar, the river, National Gallery, and tons more. The Pearse train station is 2 blocks away, and from here you can pick up trains, buses and the airport express bus.
We had a great stay.
