I really enjoyed my five-night stay at Marie's! She was very responsive leading up to the trip and even that morning when I was at the airport unsure of what to do about the electricity converter thing (look that up beforehand, btw!). Marie was very welcoming and I felt comfortable chatting with her and feeling right at home. She's also just a badass lady (can I say that?) who is really smart and active in many social causes.
The place itself was within walking distance of pretty much everywhere I wanted to see, but there's also a few bus lines that go through the area very often that can take you where you're looking to go.
All in all I had a fabulous trip in Dublin and staying at Marie's was a wonderful part of my experience! I would stay with her again if I could!
