Hi @Nancie5
As long as you make very clear in your list that you only have a fridge, microwave and toaster.. saying that, pizza is one of the most common "traveler" foods, so the lack of oven would put some guests off.
If a person is booking for over a week, and come with friends, or specially family, they will expect a kitchen.
It will limit your appeal, for sure.
Most people book airbnb because of the cooking and the washing facilities, specially longer term (at least that is my experience in London)
