20 year old, looking for a room for 5 months

Hi! I'm a 20 year old girl coming from Italy to Evora for my 5 months long Erasmus.
I will come in Evora from Mid-September to January/February, and I'm looking for a single room possibly in the city center.

The best can be a big house full of students, so we can share our time together, but I can easily fit in every situation, and... I'm not a smoker.
I'm coming on my own, so I hope I can find very nice people and room mates.

I hope you can help me finding my home there in Evora.
