What is the direction of flat of Z with respect to flat of Y?

A lives in flat 2 on odd numbered floor. X lives above A in the same type of flat and to the east of W. W doesn’t live on floor 3. So, A lives on flat 2 of floor 3 or flat 2 of floor 1. Case B: A lives on flat 2 of floor 3: Case II:A lives on flat2 of floor 2: C and H live in the same type of flat such that C lives immediately above H but below floor 3. C lives in southeast of W. E lives to the west of C. E and G live in the same type of flat and E lives immediately above G, this is not possible in case II(b), so case II(b) is rejected. G doesn’t live in flat 1, so case II(a) is rejected. So, E lives in flat 2 of floor 2 and G lives in flat 2 of floor 1. C and H lives in flat 3. Y and B live in the same type of flat such that Y lives immediately above B but not in flat 1 Floor number on which Z lives is higher than D,whose floor number is higher than F. So,Y lives in flat 3 of floor4.B lives in flat3 of floor3.Z lives in flat1 of floor 3,D lives in flat1 of floor 2 and Flives in flat 1 of floor1. The final table is given below:
