Hi Fatima - I can't comment on your first question since I haven't experienced it, but I would strongly recommend that you NEVER accept any kind of payment outside of Airbnb. This is a common way that scammers operate and you're putting yourself in a really terrible position if you do that. You won't be covered by the Airbnb insurance and are basically on your own at this point. Also, if they don't show, there is any kind of problem at all, etc. you will have no recourse. Don't do it!! I know in the beginning you just want to book as many trips as possible, but you also need to make sure they are the RIGHT people - be patient and it will happen, I promise. Good luck!
