Feng shui cures for an appartment

[vojkanst]

Hello,

I have recently moved into a small one bedroom apartment. It has narrow rectangular shape. I noticed a few things that seem suspicious to me:

1. From the main entry door, which is on the east, starts the corridor without any windows so from inside, an entry looks dark all the time. Corridor takes north-east part of the apartment. Does this require some feng shui cure?

2. Kitchen is in the central part of the flat and is part of the corridor. Is this bad?

3. Bathroom (especially bathtub and toilet seat) takes north side of the apartment and the north part spreads through the wall into the living room some 1m. Is this bad and if so which cure should be used? I read that a plant in a bathroom in the north is a good cure, maybe that's wrong but my bathroom has no windows so no plants could be placed there.

I would really appreciate some advises.
