Responding to your edit comment: I've found hotels and apartment-hotels with kitchen or kitchenettes through Expedia and their subsidiaries in Germany, Poland, Mexico, and Brazil. Agoda offers similar features, but I've not tried it out yet.

They're usually well stocked with most of the things needed for a basic meal.

I use them versus AirBnB because they seem to look out for me very well. I've had minor hassle getting a refund only once in last twelve years, but they did come through for me. I also like the simple reward program. They've added some fees in the last few years, but it's still good.
