Looking for accomodation in mid to late September

Hello, My name is Charalampos Katsanakis (I come from Greece) and I have been made an offer in a PhD program in Chemistry in the University of Southampton. I am looking for a house with 2-3 other people, no issues with genders. I'd prefer a quieter lifestyle to be able to concentrate while studying at home. I am very easy to talk to and very welcoming. I am thinking of moving in mid to late September. The budget per person should be around 200-250£ per week.
