In September I will be working as an English Language and Cultural Assistant at an elementary school in Sevilla (barrio Santa Cruz).  I am 22 years old and wondering what an ideal neighborhood would be to look for housing. I would like to live with Spanish university students or young adults. Also, somewhere that is not too expensive, as I will only be making 700 euro/month

We live in Sevilla province, but we are an hours drive from the city. The city is very expensive and I guess on your wage it be hard to rent in the city center.  You will find that most students of the uni live at home not like in the UK, as in Spain you go to the uni in your own province.
