hello @Yadira22 will you still be living at your flat as it appears you have been live in Host, am I correct?
I'm sure as an experienced SuperHost & delightful, always positive, bubbly CC member you will have everything sorted including msgs to send to IB Guests, linen, cleaning, toilet paper etc and it will be a breeze for you for you all!
Your guests are aware they are sharing with others as per your listing reviews so that covers that base.
Make sure you use a different key code or internet code for each set of guests for both your own & your guests peace of mind
Meanwhile if you get stuck simply use keywords here in CC as there's always plenty of great advice!
All the best for your transition to using IB - I have mine on & it usually works fine for me.
Happy Hosting!!
