Question about vapes

When smoking using a vaporizer does it smell?

I heard it didnt. I have one on its way in the mail and I want to know befor I get it.

I just graduated from high school, so I am obviously still living with rents until i go off to college in the fall.

But basically, can my friends and I use it in the basement at night when my rents go to sleep and have it smell fresh by morning?

And for nights when its me and a girl or two can we blaze it in my room with a window open? maybe spoof it?

I dont know much about vapes so any help with how much they smell...let me know
