Litterbox location - New Kitten

[Momofall]

Because of the way our very small house is the litterbox can only go in the (finished) basement.

However, with a very young kitten (9 weeks) I'm sensing it might be a lot to expect him to remember to go all the way back down to the basement if he needs to use it.

So here's the question....

Should we put a second litter box on the second floor for the time being while he adjusts and gains more bladder control?

If we do this is will have to be temporary because its not ideal to have the litterbox in the middle of our living space long term. I want to make sure I'm not teaching him that his bathroom will permanently be in the living room but I also want to manage any potential for accidents in these early weeks.
