Hello @Magdalena80,
I would be concerned. Those reviews are placed automatically by Airbnb when a host cancels unilaterally.
If a host has a genuine reason for cancelling, one that's covered by Airbnb's extenuating circumstances policy, they should've contacted Airbnb support to help with relocating guests and those reviews would not be there. This, together with removal of the profile photo, is not a good sign.
You should contact Airbnb to discuss your concerns.
Type "contact airbnb" in the "Search the community" box on these forum pages where you posted your question. Scroll down a little in the list of suggestions that appears and click on the "Contact Airbnb: A Community Help Guide[UPDATED]" one. That lists phone numbers and ways to contact them via Twitter or Facebook.
Steve.
