R and U live on the same numbered floor, but not immediately above or immediately below the floor on which W lives. Only one floor between U and P, who lives northeast of Q. T lives above S, but not lives above X. R lives on an odd numbered flat. 
Both X and S live in the same numbered flat. So the final arrangement becomes:
