Although we didn't meet Karen, we had her roommate Virginia, who was super welcome and made us feel right at home. The house is 35 min walking for the centre of Dublin.
The house is spacious and the room has everything you need and it is very cosy.
We were able to use the kitchen, which was very good, and it is well equipped. we had the company of a lovely cat that they own. He is the sweetest.
Our only issue was the heating as I think it was broken and at night we felt cold. Virginia very promptly arranged another blanket for the 2nd night. During the day, it was not an issue cause we were out working.
on the last day, Virginia was very helpful and allowed us to leave our bags. It was a good experience!
