Hi @Cc0, You are correct that entering your STR number in the location field does not cause it to show up in the description which is required by the San Francisco Office of Short-term Rentals. <sigh> I did figure out that if I type the letter "O" instead of the number "0" I can get my STR to not be removed (i.e., mistaken for a forbidden phone number).
I'm sure you have received the "call to action" emails to support home sharing due to the pending legislation that would require platforms to confirm hosts are registered before listing a property.
Regarding other hosting platforms, I do also list on VRBO which costs $399/year and they now (as of the expedia ownership) charge guests a % for each booking, just like airbnb. From what I can tell, if you are not a "small operator" (< $30K in revenue/year), listing on any platform other than airbnb will require you to make monthly filings to pay the transient occupancy tax (hotel tax). VRBO will allow you to collect the tax, but VRBO *does not* remit the collected tax on your behalf. My recommendation is to wait to list on other platforms until the pending legislation is resolved because it may require the platform to *collect and pay* the tax and VRBO is not capable of doing that.
