Stephanie was a fantastic host! Very responsive to questions or requests we had. She picked us up from our bus stop and walked us to the location, was very thorough on where everything was, suggestions on places to eat, visit, and grocery shop (Lidle was an excellent option by-the-way similar to Aldi's).
Stephanie provided local breakfast foods for us (English muffin, eggs, milk) which were great. The location was pretty central to many of the thing we wanted to see and allowed us to see much of the city by walking. We didn't purchase transportation, but if you're looking to travel around and outside of Dublin (outside of tours), the visitor leap card is pretty cheap and a better option for us than the doDublin buses.
Given the chance to visit Dublin again, I would definitely stay at Stephanie's place again.
