I spent a very pleasant week in this spacious granny flat. The hosts were welcoming, friendly and quick to solve any minor issues, and the apartment is immaculate. I stayed alone, but there's enough space for a couple or a small family, since the sofa can also become a bed. The apartment is attached to the main house but very private, with its own entrance and a view of the garden.
The location is on the outskirts of Dublin and it takes about an hour to get into the center of the city by bus. There are two lines that stop nearby, so I never needed to wait more than 10 minutes. Just don't make my mistake and accidentally stay out past when the lines stop running around midnight! It was nice to be able to get away from the tourists and feel like a Dublin local for a week.
