Hi @Isabel4763
Just one comment to protect yourself from future issues with pets. If you're severely allergic, you should ask for an exemption in advance. Else you won't be able to refuse service animals that future guests may bring (even if you don't usually allow pets).
Here's the full Airbnb policy:
Accessibility Policy - Airbnb Help Center
And here's the text (from the policy above) about exemption:
Airbnb-granted Exemption: In its discretion and in certain circumstances, Airbnb may grant a host an exemption to this policy if the host notifies us about their reasons proactively. For example, if the presence of a Service Animal constitutes a direct threat to a host’s health if the host lives in that listing.
