fángdōng rén hěn hǎo, rúguǒ zhù de shūfu, wǒ jiù xiǎng yìzhí zūxiàqu.

In Mandarin, adjectives can act as the main predicate of a sentence, so you usually do not need a verb like to be before them.

So:

• 房东人很好 = The landlord is nice / The landlord is a nice person

Using 是 here would sound unnatural in normal speech.

A very literal breakdown is:

• 房东 = landlord
• 人 = as a person / in terms of character
• 很 = very / often just a natural linker here
• 好 = good, nice

So Chinese does not have to say The landlord is nice with a separate is.

人 here emphasizes the landlord’s character or personality.

• 房东很好 = The landlord is nice / good
• 房东人很好 = The landlord is nice as a person

So adding 人 makes it sound a little more like:

• The landlord is a really nice person
• The landlord treats people well
• The landlord has a good personality

It is a very common Chinese pattern:

• 他人很好 = He’s a nice person
• 老师人不错 = The teacher is pretty nice

Not always. In sentences like this, 很 often does not carry strong emphasis. It frequently just makes the sentence sound natural.

So:

• 房东人很好 often means simply The landlord is nice
• It does not necessarily mean The landlord is very nice

Why? Because in Chinese, a bare adjective like 好 can sound contrastive, as if you are implying good (not bad). Adding 很 often smooths that out.

If you really want strong emphasis, you could use words like:

• 非常好 = very good
• 特别好 = especially good
• 真好 = really good

This is the pattern:

verb + 得 + complement

Here:

• 住 = to live / stay
• 得 = links the verb to a complement
• 舒服 = comfortable

So 住得舒服 means:

• to live comfortably
• to find the living situation comfortable
• to be comfortable living there

This 得 structure describes how well an action is performed or what result/state comes from it.

Compare:

• 住得舒服 = live comfortably
• 住得不舒服 = live uncomfortably
• 说得很快 = speak quickly
• 写得很好 = write well

So this is not the possessive 的 and not the structural 地. It is the complement marker 得.

Yes, the full version could absolutely be:

• 如果我住得舒服，我就想一直租下去。

But Chinese often omits repeated subjects when they are obvious from context.

Since the main clause already has 我, it is very clear that the person who would be living comfortably is also I. So leaving out the second 我 sounds natural and efficient.

This kind of omission is extremely common in Mandarin.

Here 就 means something like:

• then
• in that case
• with that condition

It connects the result to the earlier 如果 clause.

So the structure is:

• 如果……，我就…… = If ..., then I ...

In this sentence:

• 如果住得舒服，我就想一直租下去。
• If living there is comfortable, then I’d like to keep renting.

Without 就, the sentence could still be understandable, but 如果...就... is a very standard and natural pair in Chinese.

一直 means:

• continuously
• all along
• the whole time
• from now on without stopping, depending on context

In this sentence, it means the speaker wants to keep renting continuously.

So:

• 一直租下去 = keep renting on
• continue renting

It gives a sense of duration and continuity, not just renting for a short while.

Examples:

• 我一直在等你。 = I’ve been waiting for you the whole time.
• 他想一直住在这里。 = He wants to keep living here.

In this sentence, 下去 does not literally mean down. It is a directional complement that often expresses continuation into the future.

So:

• 租 = rent
• 租下去 = continue renting

This pattern is very common:

• 说下去 = continue speaking
• 做下去 = continue doing
• 住下去 = continue living there

So 一直租下去 means:

• keep renting
• go on renting
• continue to rent this place

The idea is that the action carries on from now into the future.

Good question: 租 can be used in both directions, depending on context.

It can mean:

• to rent something
• to rent something out / lease it to someone

Context tells you which one is meant.

Here, because the sentence mentions a landlord and says the speaker is living there comfortably, 租 clearly means:

• to rent a place from the landlord

So 一直租下去 here means:

• keep renting the place

If you wanted to make rent out clearer, Chinese often adds more information, for example:

• 把房子租给别人 = rent the house out to someone else

Here 想 means want to or would like to, and it often sounds a bit softer and less forceful than English want.

So:

• 我想一直租下去 can feel like
  I’d like to keep renting
  or
  I’m thinking I’d like to keep renting

It does not necessarily sound as strong as a demanding I want to in English.

That softer nuance fits well here, because the speaker is expressing a preference based on a condition:

• If it’s comfortable, then I’d like to keep renting.

Yes, the sentence combines both ideas:

• 房东人很好 talks about the landlord’s character
• 如果住得舒服 talks about the living situation
• 我就想一直租下去 gives the speaker’s decision

So the speaker is basically saying:

• the landlord is nice, and
• if living there feels comfortable,
• then they want to continue renting

That means the final decision depends not only on the landlord being nice, but also on whether daily life there is comfortable.
