@Molly396 Chef here. You have a nice home kitchen, and there's nothing wrong with it. If I was searching listings mostly for the location and just wanted to be able to make an occasional light meal, it looks totally suitable for that.
But the "Categories" feature is designed for flexible searches, where some particular thing about the home is the guest's top priority. And if my trip plans involved so much heavy-duty cooking that the chef's kitchen mattered more than the location, your kitchen is not what I'd be looking for. I don't see anything resembling ventilation for the stove, there's inexplicably a carpet in the exact space where food is likeliest to drip, the useful items I need to grab quickly are hidden in vanity cabinetry, the cooking vessels appear too small for a full-on feast, the open-plan design leaves the kitchen chaos in full view of the dining area, and the prep space is too narrow for multiple cooks to comfortably take their stations. That is all totally OK for just about every normal use of a holiday rental, but if I specifically needed a chef's kitchen, to be brutally honest, it's a nightmare.
That said, if you really wanted to market your loft as a culinary destination, I see no reason why the algorithm should crock-block you. There's no empirical definition of a chef's kitchen - it's basically just a real-estate-agent euphemism for "owner who overpaid for shiny surfaces seeks return on investment" - and anyway, Airbnb is hellbent on making search results ever less accurate.
