Francesca's place is a gem. My friend and I spent 4 days there and only used public transportation to get to and from the airport because everything was so close. We arrived a bit early but Francesca was able to get us checked in sooner than the original check in time. She was very pleasant upon meeting us (as nearly every Irish local that we met) and made sure we had all the info we needed for a successful and enjoyable stay in Dublin. I would definitely recommend staying at her place!
