20 Year old Irish Law student to study Anthropology for Erasmus

I'm a 20 year old student who will be doing Erasmus for the year here in Denmark. I am 3 years studying Law and Criminology in Maynooth University in Ireland. I'm looking for either a single or double room that's furnished and within walking distance to the campus for Copenhagens University I don't mind if it's a flat, studio, house or apartment etc. I would preferably like to share with other college students or young people and not live with a family or children.
