Le tabouret de la cuisine irait bien dans ce studio, surtout près de la fenêtre.

Le tabouret means the stool, so it refers to a specific stool that both speaker and listener can identify.

French often uses the definite article where English also uses the:

• le tabouret = the stool

If you said un tabouret, that would mean a stool, any stool, or one not previously identified.

In this sentence, the speaker is probably talking about a particular stool: the one from the kitchen.

Here, de la cuisine most naturally means from the kitchen or the kitchen one.

So:

• le tabouret de la cuisine = the stool from the kitchen / the kitchen stool

In French, de + noun can show a relationship between two nouns. Depending on context, it can mean things like:

• location or origin: from the kitchen
• association: the kitchen stool
• possession in a broad sense: the stool belonging to the kitchen

In this sentence, it most likely identifies which stool is meant.

Irait is the conditional form of aller, while va is the present tense.

Here:

• ça va bien dans ce studio would mean it goes well / fits well in this studio
• ça irait bien dans ce studio means it would go well / would look good / would fit nicely in this studio

The conditional makes the statement sound more like a suggestion, opinion, or possibility rather than a flat statement of fact.

So irait bien gives a softer meaning:

• The kitchen stool would look good in this studio

In French, aller bien can mean more than literally to go well. It is often used for things that suit, fit, or look good in a place, style, or situation.

For example:

• Cette couleur lui va bien. = This color suits him/her well.
• Ce canapé va bien ici. = This sofa looks good here / fits well here.

So in your sentence:

• Le tabouret ... irait bien dans ce studio
  means the stool would suit the studio aesthetically or practically.

French normally uses dans to mean in when talking about being inside a specific place or space.

So:

• dans ce studio = in this studio

En is used in other situations, for example:

• with many countries: en France
• with some abstract or fixed expressions
• sometimes with materials or manner

But for a room, apartment, or studio, dans is the normal choice.

French uses:

• ce before most masculine singular nouns
• cet before masculine singular nouns that begin with a vowel sound
• cette for feminine singular nouns

Since studio begins with the consonant sound st-, you use:

• ce studio

Compare:

• ce livre
• ce studio
• cet appartement
• cet hôtel

Often, yes. In this context, un studio means a studio apartment: a small apartment with one main room.

So:

• dans ce studio = in this studio apartment

French studio can also mean studio in other senses depending on context, but here the housing meaning is the natural one.

Surtout means especially or above all.

It highlights one idea as particularly true:

• Le tabouret ... irait bien dans ce studio = the stool would look good in the studio
• surtout près de la fenêtre = especially near the window

So the speaker is not just saying the stool would work in the studio in general, but that one location would be particularly good.

Près is followed by de in French.

So:

• près de = near
• près de la fenêtre = near the window

You cannot normally say près la fenêtre.

Other examples:

• près de la porte = near the door
• près du canapé = near the sofa
• près d’ici = near here

Notice that de may contract:

• de le → du
• de les → des

But here it stays de la because fenêtre is feminine singular.

French often uses articles more consistently than English does.

Here, la fenêtre means the window, referring to the window in the studio or a window already understood from context.

French generally prefers:

• près de la fenêtre = near the window

Even where English might sometimes be a little looser, French usually keeps the article.

Also, fenêtre is feminine, which is why the article is la.

The word order is very natural in French:

• Le tabouret de la cuisine = subject
• irait bien = verb phrase
• dans ce studio = place
• surtout près de la fenêtre = added emphasis on a more precise location

The comma before surtout helps separate the general idea from the more specific comment:

• generally: it would go well in the studio
• more specifically: especially near the window

You could think of it as:

• The kitchen stool would look good in this studio — especially near the window.

Not with exactly the same nuance.

• irait bien suggests the stool would fit well, suit the space, or look good there
• serait bien usually means would be good in a more general sense

So:

• Le tabouret irait bien dans ce studio = the stool would suit the studio / look good there
• Le tabouret serait bien dans ce studio = the stool would be good in the studio

The second version is possible in some contexts, but irait bien is more idiomatic when talking about furniture matching a space.

A careful pronunciation would be roughly:

Le ta-bou-ret de la cui-sine i-rait bien dans ce stu-dio, sur-tout près de la fe-nêtre.

A few useful points:

• tabouret ends with a pronounced -et sound, roughly ta-boo-ray
• cuisine sounds like kwee-zeen
• irait sounds like ee-ray
• studio is roughly styu-dyo or stu-dyo, depending on speaker
• près sounds like preh
• fenêtre has an open è sound: roughly feh-netr

In natural speech, some sounds may link smoothly, but the sentence remains quite clear and standard.
