All I can think of is publish your listing, then block all the dates off to stop people booking, then you can invite your friends (and us) to have a look at it!
We are fairly new hosts as well (since last summer) and we still regularly tweak the listing, improving directions, changing photos and making changes based on guests' feedback.
Get it published and wing it, just take the best photos you can, a good honest description is priceless, and cross your fingers.....
You've got great feedback as a guest, so you have more Airbnb experience than you give yourself credit for.
Under promise and over deliver, coupled with 20% discount for the first three bookings and that gives you a fighting chance of a great start review-wise.
Make a big thing in your listing about things that might put some guests off (eg we have dogs, so we make it very obvious.... and we get dog friendly guests!)
And stop worrying 😉
One other bunch of things... keep in mind that the guest pays Airbnb a fee on top of your own rate, it's a thing to keep in mind I understand that you also get a visibility boost with a new listing, but I'll happily be corrected on that.
You aren't getting bookings till your listing is live, we are all only here once.
Chill out, be as nervous as we were with our first guests, tell them you are new to hosting and appreciate their suggestions and feedback, and they'll be more than happy to help you out. That has been our experience.
And good luck.
