The last owners of our place installed one, and in the two and a bit years we've been here, it's hardly been used at all for cooking a meal, much to my relief. We get French and UK guests, and the French ones appreciate having a fridge to park their picnic stuff in and wash up their plates, and the UK guests like to be able to make a morning or late afternoon cuppa and keep beer cold! We offer table d'hôte and most guests eat with us. If I had to redo the place, I'd keep the fridge, sink and microwave (useful, as others have said if small people stay) but would do away with the mini-hob. I certainly wouldn't go out of my way to make space for it, if there hadn't already been an obvious place to put one. I'm pleased to say, most people clear up after themselves. Jan
