Kiwi looking for a room to rent near Stratford

I’m a Kiwi who’s recently moved to London and work professionally in Stratford. I’m looking for a flat with easy going, tidy people. During the week I’m usually in the office, and evenings are often spent at the gym. I’ve done a lot of travelling and spend my spare time writing or exploring London. I’m ideally looking for a place for at least 6 months, in or around Stratford.
