Basically how it used to work is every time you got a 3 star review or less you got a week suspension if the overall rating for your listing is low like yours.
During that time your listing is suspended but your existing reservations can continue.
It's in your best practice to avoid getting 3 star reviews (or lower) at all cost as they reveal real issues with your listing.
There is a recently added policy that if you pile up listing issues before they expire, then your listing could be shut down as well. First time it's 1 week, then it's 1 month, then it's shut down AFAIK. This is regardless of your overall rating as a host or the listing itself.
