I agree, but it is used often enough for it to be considered acceptable, in my opinion.Personally, I don't think the apostrophe is needed before the "s", but others may disagree.
It is OK to say it, but the meaning is not clear without more context.
I was taught at school back in the 1950s that the apostrophe was essential there.
Some time in the 1970s I discovered descriptivism - at school, and even at university, prescriptivism ruled. I was a prescriptivist myself when I started TEFLing in 1968, proud that, unlike some of my less well educated colleagues, I at least was able to maintain standards.When did you realise it wasn't, 5?

I was taught at school back in the 1950s that the apostrophe was essential there, and with letters of the alphabet - There are two c's and two m's in "accommodate".
