chins do like to be in places where they can see you pass by and such, but if its very noisy since its the place you are most of the day, it might not be the most ideal. could you possibly put him in a computer room/study? some people keep their chins in a bathroom if it's big enough because for playtime the bathroom is the place that has the least things to chew
personally, i keep my boys in my bedroom because i am in there a good amount of the day but not where i'm constantly making noise so they can rest. though they are nocturnal, i've gotten used to them being up at night
good luck! hope you enjoy him
