Cozy but was fine for a nice 3-day solo stay in Dublin. The place was clean, and it was very convenient to have a private entrance to come and go. Éle, my host, was easy to communicate with and quick to reply to any of my inquiries.
The place was a bit outside the city center. But it was nice to be away from the crowds, and the neighborhood was clean, safe and peaceful. To get to the city center took about 30 minutes... 15 to walk to the tram, and another 15 minute ride. But had no problem with it.
Right down the street from the flat is Kilmainham Gaol, which is definitely worth a visit. And just a little ways past that is a nice pub, The Old Royal Oak. A friendly neighborhood kind of place.
