Please make sure that you have no unforeseen changes to your itinerary. I had to add a day to my stay due to unforeseen circumstances and asked the host if he could extend my stay one more night. I did not receive feedback from him for a day until he told me "you add your stay through airbnb and we should approve it". At that point I was not sure if it was approved or not. I was not sure how to proceed. I had requested to extend my stay an extra night a week prior and he never gave me an answer. I resorted to extend a night with Together Co-living directly. Thankfully they were able to accommodate me on such late notice. Unfortunately it was at double the cost then what airbnb charges.
