Ventless dryer, renting, urgent q

Does anyone know much about ventless dryers? I'm looking to rent a place in a condo but the whole building uses these and I wonder if this will stink up my whole unit or if the neighbour's scents will travel to my unit. It's so stressful because everything else is great and I dont have much time to decide. It's one of the few places with unlived in units and that alone is huge for people like us. I didn't notice any odd smells in the 2 units I saw, just some remaining offgassing as the building is 2 yrs old.

Thank you!
