Where do you think your noise is?

There is reflection blur noise in the back room -- using interior_high should solve this, although it's quite a bit slower.

The anti-aliasing issues on the TV stand are more troubling to me, since the interior_fine preset didn't solve it.  I would alter the model, and make the gaps wider by a couple millimeters.  Maybe a 1 or 2 segment bevel or chamfer would help.

Is there a recommended gap size to avoid this? this happens frequently with my models.

it depends on the distance of the camera versus the gaps but maybe 2 mm or 3 mm?

I see what you mean - thanks Justin!

You have made your walls reflective. Although technically this is correct, in most cases the reflectivity of the paint we use on walls is so low, they don't actually appear reflective. I this regard you need to reduce the reflectivity level to 1 or 2.

It also looks like you have used a texture and applied bump with reflection. The reflection blur quality is configured in the presets, and for best performance, it's set at a level which renders quickly but there is a little noise. I did that because the noise is not particularly noticeable on most renders if materials are set up reasonably.

You have 2 choices, modify the preset or remove the bump and reflectivity (at least reduce it significantly) from the wall.
