I think that you should leave it where it is until the buds are nearly ready to open, although more light as well would be better.
The sudden temperature difference can cause the buds or the entire spike to blast, as I've sadly discovered on several occasions before finding out not to move it someplace warmer.
Would it be possible to put it behind a curtain againt the window in the living room? That way you would create a cooler microclimate for the plant and the temp difference wouldn't shock it too much.
