Firstly, the apartment is even more gorgeous than the pictures show - breathtakingly beautiful from the sunny yellow entrance hall to the high-ceilinged apartment itself. We didn't meet Karin, but her instructions on how to reach the house and what to do couldn't have been clearer. She was also really quick to reply to my messages. Karin's housekeeper Jackie took in our bags on arrival and was really friendly. On our second day Jackie even brought round a home-made cake which was delicious and such a thoughtful thing to do!
The apartment was spotless, with a very comfortable bed and a lovely hot shower. The kitchen was well equipped with everything we needed including some very good filter coffee. It's about a 20-25 minute walk to the centre which was fine with us, and there seemed to be lots of transport options for getting about. The only tiny drawback would be the traffic noise from the street outside, which is to be expected due to the age of the building and the location. But once the shutters are closed and the evening gets on a bit it's really not bad at all and didn't impede on our stay whatsoever.
We had a fantastic time and would absolutely recommend this apartment for a place to stay in Dublin.
