Vull llogar aquest pis.

Catalan often drops subject pronouns because the verb ending already shows who the subject is.

• vull = I want
• so jo is not necessary

So Vull llogar aquest pis is completely natural. You can say Jo vull llogar aquest pis if you want extra emphasis, contrast, or clarity.

Vull is the 1st person singular present tense form of the verb voler, meaning to want.

A few present-tense forms are:

• vull = I want
• vols = you want
• vol = he/she/it wants
• volem = we want
• voleu = you all want
• volen = they want

It’s an irregular verb, so the form vull has to be learned as a set phrase.

After voler in Catalan, the next verb normally stays in the infinitive.

So:

• vull llogar = I want to rent
• literally: I-want rent

This is very similar to English, except Catalan does not use a separate word like to before the infinitive here.

Llogar means to rent, to lease, or sometimes to hire, depending on context.

In this sentence, with pis meaning apartment/flat, it means to rent in the housing sense.

A useful thing to know is that llogar can sometimes describe either side of the rental situation, so context matters. But in Vull llogar aquest pis, the natural interpretation is I want to rent this apartment.

Here, pis means apartment or flat.

In Catalan, pis can also refer to a floor/storey of a building in some contexts, but when someone says llogar un pis, it clearly means to rent an apartment/flat.

So in this sentence, pis is definitely the home, not the floor level.

Because pis is a masculine singular noun.

In Catalan, demonstratives have to agree with the noun in gender and number:

• aquest pis = this apartment/flat
• aquesta casa = this house

So:

• aquest = masculine singular
• aquesta = feminine singular

Since pis is masculine, aquest is the correct form.

In standard Catalan, a demonstrative like aquest normally replaces the article.

So you say:

• aquest pis = this apartment
• not el aquest pis

This works like English this apartment, not the this apartment.

A rough guide is:

• vull — the ll is a special Catalan sound. Traditionally it sounds a bit like lli in million, though pronunciation varies by region.
• llogar — begins with that same ll sound
• aquest — roughly ah-KEST
• pis — like peace, but shorter

A broad pronunciation guide could be:

• vull llogar aquest pis ≈ bool lyo-GAR ah-KEST pees

But that is only an approximation. The hardest part for English speakers is usually the ll sound.

Yes. That sentence is also correct.

The difference is mainly emphasis:

• Vull llogar aquest pis = neutral, natural
• Jo vull llogar aquest pis = more emphasis on I

For example, jo might be added if you are contrasting yourself with someone else:

• Ell no, però jo vull llogar aquest pis
  Not him, but I want to rent this apartment

This word order is the most natural basic order:

• Vull = verb
• llogar = infinitive verb
• aquest pis = object

So the sentence follows a very normal pattern for Catalan.

You can change things for emphasis, but the standard learner-friendly version is:

• Vull llogar aquest pis

That is the best version to remember first.
