23 year old guy looking for a room/roommate in Dublin, starting from August until February

I am a student from a hotel management school in The Netherlands, and I will be having my internship in two of the O´Callaghan Hotels in Dublin starting this August 2016. For this reason, I am looking for any type of accommodation but preferably a room in a shared house or apartment (within the city of Dublin). I do not mind about the age, gender, or lifestyle of my roommate as long as I get enough privacy and a safe place to stay in. I am a polite and open-minded person. I have lived in different countries and is exposed to different cultures, which makes me comfortable with people from different backgrounds.
