You can use a constrains method decorator:

@api.one
@api.constrains('start', 'end', 'room_id')
def _check_room_overlap(self):
    overlaping_bookings = self.search_count([
        ('room_id', '=', self.room_id.id),
        ('start', '<', self.end),
        ('end', '>', self.start),
    ])
    if overlaping_bookings:
        raise exceptions.ValidationError("The room was already booked")
