changes to my account

Good afternoon,

I have just added my B&B mountain lust accommodation, but I have a few questions:

1. It is an apartment for 2 persons, but there is a sofa bed for max 2 children up to 12 years. How can I adjust this?
2. I want to indicate for a number of weeks that they can only book it for at least 10 days, how can I set this up?
3. I have synced my calendar with Airbnb, but where can I find the code to add this in Aibnb as well?
4. Now the site says: We're sorry, but this property isn't taking reservations on our site right now. Is this because I haven't received the code from you yet?

Thanks in advance,
