You can assume that the apartment's kitchen or kitchenette has utensils, cutlery and crockery for the stated number of persons. But do not expect more. The equipment varies depending on the country and local conditions. Coffee maker, toaster, peeler, whisk, cheese slicer, etc., are not normally in the equipment.
For stove and hot water, gas is common. Contact reception/key offices if something is missing or if the gas runs out.
