Hi kmleong,
For a superbly clean up-kept house, normally people with maid would sweep and mop the whole house twice a day (everyday morning after breakfast and night after dinner). My cousin's house is superbly clean with the maid cleaning everyday.

What I am suggesting is not to hire a maid to clean, myself I am staying at a condominium like your apartment, I don't have a maid to do these, so this is what I practice (almost), you might wanna consider some of these important cleanings:
1. Sweep and mop once a day;
2. Wash necessary fabric (sofa, curtain, table cloth, etc) items once a month;
3. Wipe surfaces of each items (cabinet, tv, table, window, etc) once a week;
4. Throw away unnecessary items placed in living room;
5. Clear and wash your rubbish bin every day;
6. Get a safe air freshener place at center of living room to keep the air breezy
7. Be observant no matter where you go around in your aparment, you might find proof to what leads to the bad odor!

Good luck!
