Christian's place is cosy, clean and comfortable. Communication was excellent and the directions very clear. The street is busy but in the apartment there is no noise. We were two couples and spent a long weekend there. All went great.
The tram (Luas) stop of Heuston station is very close by, making it easy to reach when you arrive with the airport shuttle. City center is 10 minutes with the tram or a casual walk of 30-40 min. If you don't want to book a place in city center, this place is a well connected alternative. Recommended.
