Young Japanese couple looking for a flat

We are a young Japanese couple looking for a flat in zone 2/3, either a 2-3 bedroom or a self-contained flat will do as long as it is less than 1900 a month bills included.

We both cannot live in an unclean environment, and since our current flatmate does not share this standard with us, we are moving out. My partner always keeps his surroundings very tidy and I am confident we can be trusted with properties.

We do not have too many requirements for flatmates. My partner and I are both qualified martial artists in a Japanese martial art/sport.
