Bonjour Benoit,
It's great that your daughter is coming to Dublin for her internship!
First of all, I'd suggest having a look at university student accommodation (such as
Trinity College) or also wider rental platforms that have student accommodation available, like
daft.ieAnother tip would be to ask her home university or the company where she'll be working for any leads, as it can be though to look for a place to stay remotely. Another great place to look are Facebook groups of international students and expats alike.
I hope this helps! Let us know if you'd like tips to
explore Dublin and surroundings to share with your daughter.
A bientôt,
Antoine
