I stayed in Kevin's house with colleagues when visiting Dublin for a conference. It is very well located, the house is lovely with plenty of space and very comfortable beds. One of the bedrooms is located through one of the others, so you would need to be good friends who don't mind at least partly sharing that space. It wasn't a problem for us at all. The showers are very good, there were plenty of towels and Kevin had left scones and apples which were lovely touches.
