23 years old boy, looking for accommodation in Porto

I'm 23 years old italian boy and I'm looking for a room in an apartment in Porto. 

I'll be there from mid february to mid july, I'll do a trainsheep in Universidade catolica portuguesa. I'd like to find a room with bed, wardrobe and window, and living in an apartment with other portuguese students or erasmus. In mid december I'll be in Porto for 3 days to see the house. If anyone have a suggestion, please contact me!
