Sixteen individuals — A, B, C, E, N, O, P, Q, R, S, T, U, V, W, X, and Y — reside in two flats (Flat 1 and Flat 2) of a four-floor building. The floors are numbered from 1 (lowest) to 4 (highest). Flat 1 is located to the west of Flat 2. Flat 1 on floor 2 is directly above Flat 1 on floor 1, and similarly for Flat 2. There are eight married couples, each couple living together on the same floor and in the same flat. Names starting with a vowel indicate females, who live only on even-numbered floors. The following conditions apply:

• A lives directly above P’s spouse’s flat.
• A’s spouse lives in an odd-numbered flat.
• O and Q live on the same floor.
• T lives to the northeast of U and below E.
• Q does not live in the same flat as E.
• B lives on an even-numbered floor and two floors above N.
