Does the bold part lack punctuation?

No punctuation needed.

Personally, I would have written "a 160-square-metre cabin". That is, in the compound phrase "number-square-metre", the words in full, and joined by hyphens. If a compound phrase (number + noun) serves as an adjective and comes before the noun it modifies, it usually needs hyphens:

a three-and-a-half-bathroom home
a four-bedroom townhouse
a 600-square-foot studio
a 2,000-square-foot, fully renovated four-bedroom, three-and-a-half-bathroom home

Note: Americans usually write "meter".

A person who is a fool and a coward hiding behind a mask of anonymity thumbed me down, yet what I wrote is still true.

Hi centrox,

What you have posted above shouldn't be here. Am I right?

You are not right.

I don't see any anonymous poster here.

Thanks for pointing out what you meant. I can understand why you are upset.

centrox, I restored your thumb. Everything you said is correct.

I don't know if it's the same person, but someone often votes me down on the beautiful animals thread. Why? Dunno.

I am aware that some people thumb posts down in order to collapse them, as a kind of "mark as read" thing, and they do not mean to express displeasure or disagreement.

I'm aware of that too. However, this happens a lot. Although it may be someone collapsing a thread occasionally, I believe that someone is giving me a thumbs down for other reasons.
