TL;DR: Book this place now! You'll thank me later.
The long version:
we spent 10 days in Ireland and onto other European places, and on our return, we have 1 night of layover in Dublin and decided we do not need to be in the Dublin center and would rather be closer to the airport. So we found Becky's place.
As I said, I previously spent 10 days in Ireland recently and stayed in 4-5 star hotels, but Becky's place was better than all those hotels. She gives you a home. Instantly when we walked in and greeted by her, it felt like this could be home. The space is huge, the bed is comfy, the place is stock with everything you need, with cute homey touches. We regret we could not stay for longer than a night! Although a bit far from Dublin Center, you can likely get there easily with public transportation or even walk for about 20-30 minutes.
Trust me, it's worth it. :)
