l'Ambassade du Italie en Dublin

information
My name is Debora, I am 24 year old and I am about to come to Dublin to study, therefore I need to find a furnished flat to rent, but I have no idea how it is working over there. I checked up a large number of real estate websites on internet but my lack of information regarding how a foreigner can come and rent a place in Dublin is not helping if added to the other issues I meet. I am not working but the rent would be paid by my parents, and a French friend of mine will post bail for me, all those details seems to scare off the majority of the landowner.
This is why I really need a hand to get the chance to step in Dublin the saint Patrick capital city and get to learn English. That journey would enable me to develop the need skills in my formation to become a translator.
Any help or information would be very much appreciated.

Thank you for your kind assistance.
