@Hannele6 Hi whatever is out/available is fair game ie guests can use/consume it.
If you really don't want it used, have a private locked cupboard. I have a big locked cupboard in my laundry with my own food and other stuff. And a freezer in a room they can't access.
Don't worry about breakages, it's usually minor, just expect to replace glasses or crockery over time. That's just wear and tear, don't expect to charge guests for that. If it's fragile and you don't want broken, again, lock it away.
I actually have concerns with hosts who just open their house up as is. Because how do I know as a guest that you've cleaned everything before my arrival? eg the fridge. How often does a fridge get cleaned if you don't empty it regularly. The downside of not putting things away is that you may get rated down on cleanliness unless you are completely on top of every window being clean, dusted, no mould etc. It's a next level of cleanliness for hosting guests compared to living in it yourself. I am constantly vexed even in my holiday property that cleanliness is my lowest rating attribute even though we are pedantic about cleaning everything, from blowing leaves off porches, wiping down walls, cobwebs etc, windowsills, cleaned blinds etc. It doesn't take much for guests to rate you down on cleanliness if it's not perfect! I had one guest gave me a lower rating on cleanliness and I asked why, and he said because he found a few dishes that were dirty (his definition was something that was encrusted on it after dishwasher probably from a previous guest).
BTW I'm about to do something like you for another property I live in, and I've been carefully thinking through a second fridge and a second cupboard in the kitchen, a bit of building work reconfiguration required to do this long term.
Afterall you want to provide a fabulous experience for guests. Providing your whole home is a whole different level of expectations to meet in my opinion. But you've had good experience doing a room so you are up for it! It's those that don't even have any hosting experience that struggle trying to do this successfully.
Hope this helps
