Slice offers a simple solution to a simple problem. You have a stranger staying in your apartment for three days next week. They are from a country you’ve never heard of. You don’t know if their local customs involve defecating on the walls and setting fire to your shag carpeting. Instead of hoping Airbnb covers it, or thinking your rental/homeowners insurance even knows what the on-demand sharing economy is, you can purchase an as-needed policy for just those three days from Slice via a mobile app.
