I assume "todomerumono" or 留める物 is the "a place to stay".

Something like "留める物が要する"?

Since 要する is to need... It's a very direct translation.

I'm trying to write stories in Japanese to learn words, and this story
involves the heroine asking for a place to stay. The land is fantasy/magical
and pre-industrial in case that affects word choice.

--- UPDATE ---

The heroine is saying it.

question
word-choice
How does one say "I need a place to stay"?
You know, for a first guess, that's really good. In modern Japanese I would
probably say something like

泊まる場所がいる

泊まる場所 (tomaru basho = crashing/staying-place = a place to stay)

が (particle GA)

いる need

You can also riff on what you've got by saying

泊まる場所が必要です

必要です (hitsuyou desu) = is necessary

要する, although properly placed conceptually in translation, actually means
something like "in summation" and in usually used in the form of 要するに.

(simple english / japanese example) There were three thousand blue flowers,
ten thousand green flowers, and five thousand white flowers, 要するに, there were
a lot of flowers.

I think it's more common in Japanese to use 'want' instead of 'need' (or just
implications of necessity/desire) when you're talking about oneself--
otherwise, it comes off as a bit strong or desperate. If the heroine is indeed
asking in such a way, then sova's answer would work.

Otherwise, here are some roundabout (but more 'Japanese') ways to go about it:

> 泊まれるところを探していますが…  
>  I'm looking for a place where I can stay [and would you happen to know of
> any?]...
>
> 泊まる場所、ありますか？  
>  Is there a place to stay? [Hopefully in your house?]
