Nice. You can try changing caustic blur value and/or use hotpixel option to fix that noise.

Thanks alot :)

I decreased the hotpixel removal to 0 but I feel the image lost a little of its sharpness

Yeah, you probably never want to put the value to 0, try .3 to .5 values and then check again, another thing to is take the image into an image editing application such as photoshop and add slight noise over the whole image to bring back some sharpness. What about filter size setting, check you have it set to a value of 1.2. Also there still does seem to be noise on the table despite the overall image being quite clean. Can you lower the resolution of your light emitters to help reduce this.

the noise comes from the candle.
turn off the flame, try to lower the emission and add the flare in ps.

Yes that's sample which also exist in the blackbody emissions properties
