The week I spent in Frances' house was wonderful.
Her house is in a residential suburb 7 km outside of Dublin center, and you can get there by bus no. 29a or by the DART train. Both are quite crowded during rush hour.
The benefit of Frances' house is that it's really quiet (no traffic outside, not even people on the street) and you live there almost like a family member with Frances, her husband Dave and a cute little dog.
Frances is very caring about your well-being, just like your own mother or grandmother would be ;-)
