I offer a room in my home with access to a living/dining room, dining room and garden.
When the summer changes took place I was correctly put in the Rooms category.
On checking my listing today I saw Airbnb had changed my category from Rooms to 'Place to Stay' which is a category for hosts who don't offer shared facilities and I no longer show up in the Rooms category.
I have just spent nearly an hour on the phone to Airbnb trying to explain what the issue is and asking them to change it back. Customer Services seem unaware of the new categories system and what I was asking them to do.
I would suggest other hosts who offer Rooms check their listing to see that their listings are still in the correct category.
I also had to contact them last week because they showed my listing as being shared with other guests which is not the case.
