We stayed two nights with Marta and Francisco. We had a bit of a hiccup with checking in, but apart from that everything was absolutely perfect. The flat, the room, and the building are super clean and secure. It is in a great location for exploring Dublin and there are supermarkets, pubs and restaurants at their doorstep. However, the apartment complex itself is quiet and we didn't hear anything overnight. Marta and Francisco were really hospitable and thoughtful - they even picked up some pastries for a snack during the day! The space is great for a couple, and would work really well for a long stay because the apartment itself is spacious. We caught taxis to and from the airport, but either of the buses (private or public) would work fine if you don't have a lot of luggage. Just have exact change if you plan to catch the public bus - the drivers don't quite embody the image of Irish hospitality ;)
