Floor 1 is the ground floor. Flats are named by floor and letter: 2B is floor 2, second from the left.
Left and right are as you see the building from the street.
Hear: sound travels through shared walls, floors and ceilings, never diagonally. "I can hear Ana" means Ana is next door, directly above or directly below.
Next door: same floor, side by side.
Directly above: same column, one floor up.
In my column: same column, on some other floor.
Corner flat: an end flat on the top floor or the ground floor.
Left or right end: the first or last flat on that floor.
Floors above mine: everyone on a higher floor, not just the one above.
Some buildings have empty flats. The count is shown above the tenants.
Every clue is true. Every building has exactly one answer, and you can reach it without guessing.
Sundays have a twist: one tenant always lies, so everything they say is false. Mark the liar before you turn the lights on.
