The location is perfect for seeing all of Dublin and getting around. The building is secure and I found the security guards to be informative. I would highly recommend The Landmark pub, which is only a few blocks from the flat as well as Sophie's Restaurant Bar & Terrace and Las Tapas de Lola, both a few blocks away.
The flat itself is comfortable. The eggs/bread/milk/butter left for us was nice. The bedding needs to be updated and there are a few things that need fixing within the flat. Our stay was only for a couple of weeks, so it wasn't a huge problem.
All in all, it's a great base to see Dublin and in fact, all of Ireland from.
