Karen's place is a really good choice if you need to get a nice accommodation quickly from airport for a reasonable price. The surroundings is quiet and calm and the city is close.
Karen is a fine host, she has everything prepared and she welcomed us with a cup of good tea, which is something you need after a flight and driving on the left side. :) We spent part of the evening with Karen's lovely daughter who is both fun and cute.
The place is as well a perfect start point for Wicklow mountains, but also for trips to Dublin. We would not hesitate to stay here again.
