I stayed here with 3 other girls, and we had an amazing time. The kitchen is fantastic, the main living room was comfortable, the bedrooms were great, and the back patio was beautiful! The location is within a 10 minute walk to the train station into Dublin, with the train taking about 20-30 min. Dalkey is such a cute town with lots of restaurants and scenic views. Mary was a fantastic host, she answered all our questions, left instructions, and even picked us up at a bus stop! I definitely would stay here again.
