I would not rent an apartment that smelled like curry. It's such a pervasive smell. I like Indian food while I'm eating it, but I don't want the smell in my home. I like fish enough that I make it at home, but I keep a fan going in my kitchen, and I don't usually fry it. The oil gets on the walls and sticks, and it's just full of fish smell. I imagine oil has something to do with why the smell of Indian food sticks.
I don't agree with those who would burn scented candles or use Febrese and its scent cohorts. Then you have two powerful stenches. Lose-lose.
I had a cubicle mate once, who was from Pakistan, maybe. And he came into work every day reeking of curry. Curry and dirty clothes, actually. I asked to be moved eventually, but changing cubicles is a lot easier than dealing with an apartment that stinks.
The last time I rented an apartment, I didn't smell any with Indian food, but I didn't rent what would otherwise have been a perfect place because it stank so of scented candles. There's no way I wanted to live there, and I told the landlady exactly why. She offered to have it cleaned, but it stank so much, I just couldn't do that to myself.
Until the day when landlords wise up and expand the "no smoking" clauses in leases to include other stenches, I wonder if it's possible for Indians who come to America, presumably to go to school, to learn to cook non-Indian food. And maybe for all people not to use scented candles, incense, and air "freshener" in rental apartments.
