34 year old PhD student looking for a private room and bathroom in Dublin 2

HI -

I am a recently accepted PhD student to Trinity College. I need a private room with a private bathroom in or around Dublin 2. I have was born in US and brought up in Saudi Arabia and have completed my bachelor and higher education in the states therefor I am caught between two different cultures which compelled me to enjoy and cope with other people of different backgrounds. I am clean but not analretentive lol.. friendly, respectful and tend to be quite most of the time. I smoke and drink socially but I lean toward not to party too much.
