What's the grammar behind ヤカンのある部屋?


I tried to make a sentence saying that since I don't have the key I cannot go
inside the room that has a kettle:

> 鍵がないからヤカンがある部屋に入れなかった

But I was told that it sounds better if I changed it for

> 鍵がないからヤカンのある部屋に入れなかった

What's the grammatical reason that explains this?




The grammar behind this is explained in this question, although you may
already know this: [How does the の work in
「日本人の知らない日本語」?](https://japanese.stackexchange.com/q/12825/5010)

I personally think this sentence is perfectly fine and natural regardless of
whether you use が or の. Someone might feel the sentence sounds slightly more
"soft" or "sophisticated" with の, but this is very subjective. I think you can
safely ignore the difference unless you're interested in aesthetic writing.
