Hi,
my sister and her boyfriend moved to Clane last year, she paid 289k for a 3 bed semi with attic conversion and conservatory, similar house on her road w/o conservartory and attic conversion went for 320k recently.
They love the village, some decent pubs....Jones' and Manzors are 2 they like, it also has some nice restaurants, the Zest Cafe is good.
Cant tell you much about the commute as neither of them work in the City centre, as the previous poster said, traffic can be quite heavy but seems to move quickly.
There is no nitelink, the nearest one would be Maynooth, i think.
Taxi wise, its about 50 quid if you can find a taxi driver to take you out that far, my sister tends to stay with us if she goes out in town.
Hope that helps.
