Put the trash can under the sink if possible to help maintain flow in your small galley kitchen, or place it at the end of the narrow space. Keeping it near the door will make taking the trash out easier, but then you are also greeted by the trash can as you enter. In this case, make sure you have a sleek and streamlined design, in stainless steel or a color. This 'totem' design trash can by Joseph Joseph, at Amazon, is being described on TikTok as the 'world's most perfect garbage bin' with its three sections for recycling, food waste, and general waste.
