I absolutely recommend Sean and Mary's place if you are planning a visit to Dublin. Monkstown is a lovely seaside location that is worth staying: the airbnb is at 1 min distance from the park along the coast and you can easily go to central Dublin with buses (46a) or the DART (train line). Very close to the airbnb you can find a convenience store (Spar), open from 7AM to 11PM, plus several restaurants, pubs and shops. No need to say more because Mary and Sean will be very welcoming and helpful! This place is a must.
