Пост в Porto, Porto District, Portugal

Hi!! I am an italian girl and I will be Erasmus student for a while in Porto next year (february-june). I know it's early, but I wanted to ask around if anyone knows about possibilities to have a room/flat to rent or be helpers/volunteer somewhere. I will be with my daughter (we are both travellers :) ) and I would like to make my stay an experience with locals, to share, learn, enjoy Let me know freely! ps. i can also offer a house exchange with Milan, Italy :D
