Liam has a very nice, modern sixth floor apartment in Smithfield/Haymarket Square. It's comfortable, especially if you only need one bed, but the pull-out couch is easy and comfortable too. The apartment is close to many of the main Dublin attractions (15-20 minute walk usually) and far enough away to still be peaceful. The place is also right next to a lot of mass transit options and nice cafes. Make sure to read the directions Liam sends beforehand to ensure an easy check-in.
