How do I count all rooms in this model?

Question

Hello, I have this model here which has all available rooms.

I want a way to be able to count all available rooms but I don't particularly know how because these rooms are shown as a tree table in xml:
string ="Hotel Room" >
name ="name" />
name ="categ_id" />
name ="list_price"  string ="Room rate" />
name ="status" />

I have tried creating many2one field to this model to get the records but it shows none. Could someone help me?
