Hi @Sue728
In Your profile You state:
"I am checking out Airbnb for the first time and one day become a host."
As it looks You've got enough space in Your home. Why don't You throw the party in Your own place?
This would be a good exercise to later open Your listing for hosting parties to the general airbnb audiance.
If hosting parties at Your place is not an option for You pls note, that there is a "parties/events allowed" box You can check in the airbnb search filters. I was just looking for a party-place for the weekend april 26 to 28 for 14 guests. 2 listings pop up in the greater London area: 1 at Picadilly Circus which sells for 4749 Euros for the weekend and 1 at Mayfair which sells for 2528 Euros.
