Excellent, excellent service. Warm, friendly, welcoming, even when I arrived unexpectedly early. The host went above and beyond, helping me with transportation and letting me eat breakfast a bit early before my flight. The bnb was very clean. Tea and coffee were provided. I will certainly be staying at Marie's Bed and Breakfast anytime I return to Dublin! It is worth noting that the location is a bit out of the way but a taxi from/to the airport takes 10-15 minutes (depending on traffic) and the city is accessible through public transportation or a 2 hour walk if you're up for it!
