£ 500 /month - 1 rooms - 2 couples looking for house/flat to rent from July 1st-Sept

We are four honest graduates who need to find a short term let from July 1st until Beginning=middle of September. We need two room as we are 2 couples. We don't need a beautiful house or anything, just somewhere to sleep. We currently live in Brighton but cannot stay in the same house due to long term contract committment which we cannot give. Please get in touch if you know of any such property we can rent short term. Cheers.
