Joe and Sharon were excellent hosts, and the flat is well- located, modern and very clean. I slept on the pull out sofa bed in the living room, which I found very comfortable. Sharon, Joe's, went out of her way to meet us for an early bag drop at the apartment since we'd just landed that morning, and spent a good half an hour guiding us around Smithfield Square to give us some bearing on the neighborhood. It's well-located in a hip area (I've never seen that many coffee shops within a block of each other!). We frequented the Temple Bar area and went to the Guinness Storehouse, and both walks were enjoyable and about 15-20 minutes. We liked being able to head back to a quieter area at the end of the night.
It's hard to provide any negative feedback about our experience. If you're looking for quality and affordable accommodation within walking distance to the major sights in Dublin, search no further.
