Cynthia sent us the accurate and detailed description of how to get to the apartmemt from the airport (including a video of where to go after taking a shuttle bus) which was very helpful. She was very welcoming and met us with hot tea and sweets that was super nice after a long flight.
The apartment was clean, the kitchen was equipped with everything one would need to cook, the bed was very comfortable.
There are at least 2 bus routes going to the city center, but be aware of the strikes that are still happening in Dublin - if it's a strike day the only way to get to the center is taxi (or walking).
That was our first experience with the airbnb accomodation, and we couldn't enjoy it more.
