The flat looked exactly like the pictures. It was truly a beautiful place to stay and good value as well. I loved the architecture and all the trim. 20 ft (6.5 m) ceilings were especially impressive. The bath and kitchen were well equipped and Karin even provided a very nice welcome basket of fruit.
It's a 10 min walk to O'Connell St and about 30 min walk to Christ Church and Dublin Castle which are both close to Temple Bar if that's your thing. St Pat's is another 5 min further.
The flat tends to be a little cool due to the high ceilings so bring a jumper. And the wifi was a bit spotty at times. But all in all, I would certainly recommend staying there. One caveat for Dublin, no car unless you have on sight parking otherwise having a car is a pita.
