how I can update the address of the hosting place?

I forgot to add the leter near the number (instead of 34 j , I wrote just 34)

Hi, @Mojca9. I just looked it up in Help, and followed the directions, but they do not work. I expect you tried that as well. Do you have Twitter? (If not, you might want to set up an account just for this one thing. It's free.) Send a DM (direct message) to AirbnbHelp and see if they will stick that J in for you, or tell you how to do it. Will you let us know if they do tell you how you can do it yourself?
