A great initiative. Please stay safe, and enjoy :)
If you have been impacted by the floods, you can get free accommodation with Airbnb hosts until April 8. To apply, you'll need an Airbnb account and once you're logged in, you'll be asked a few questions about how you have been impacted. Airbnb will review the responses and then get back to people typically within 24 hours. Once Airbnb approves you, then you will be able to see the places you can stay at for free. Once you find a place that seems suitable for you, you can reach out to the host.
