it depends on what you are cooking. if just vegetables, then its ok. if fatty meats or sugary yakitori, then there will be lots of smoke. we had to open our floor to ceiling windows and it was still very smokey. binchotan is really expensive to burn, i just use compressed bamboo, it's also smokeless. i like low profile grills like this round one so you don't need to reach high for the food. if doing yakitori, then bincho grill is excellent but not really for indoor use. yakitoriguy on youtube has done reviews on most of the popular models.
