見晴らし is a noun meaning view, outlook, or how well you can see out over the surroundings.

In this sentence, 見晴らしもいい means the room has a good view. It often suggests an open, pleasant view rather than just the ability to see outside.

A very common expression is:

• 見晴らしがいい = to have a good view

風通し is a noun meaning airflow, air circulation, or ventilation.

So 風通しもいい means the room is well ventilated or gets good airflow.

A common expression is:

• 風通しがいい = to have good ventilation

Literally, it is about wind or air passing through well.

は marks この部屋 as the topic of the sentence.

So the structure is basically:

• As for this room, the view is good, and the ventilation is good too.

Japanese often sets up a topic first, then says things about it. That is exactly what この部屋は is doing.

Here, も means also or too.

The speaker is listing good points about the room:

• 見晴らしもいい = the view is good too
• 風通しもいい = the ventilation is good too

Using も makes the sentence feel like a list of positive features.

If you said:

• この部屋は見晴らしがいい。

that would simply mean This room has a good view.

But in this sentence, the speaker wants to say not only one thing, but also another thing, so も fits naturally.

〜し is a very common way to list reasons or list qualities.

Here it connects one positive point to another:

• 見晴らしもいいし、風通しもいい。

It gives a sense like:

• It has a good view, and also good ventilation.
• It has a good view, plus the ventilation is good.

A useful nuance of 〜し is that it often sounds like this is one reason, and here is another. It can also suggest there may be even more good points besides these.

Because し is being used to connect the first item to the next item.

So:

• 見晴らしもいいし、 = the view is good, and...
• 風通しもいい。 = the ventilation is good.

The second part ends the sentence, so it does not need し.

If the speaker wanted to keep trailing off or imply more items were coming, they might say something like:

• 見晴らしもいいし、風通しもいいし…。

That sounds like The view is good, the ventilation is good, and...

Good question. Japanese has more than one way to connect ideas.

With an adjective, one possible connection is 〜て:

• よくて from よい / いい

So a sentence could be connected in a different way. But 〜し and 〜て do not feel exactly the same.

〜て:

• more neutral linking
• often just connects descriptions

〜し:

• lists reasons or strong points
• often sounds like the speaker is giving supporting points
• can imply among other things

So here いいし is very natural because the speaker is presenting reasons why the room is good.

Also note the irregularity:

• dictionary form: いい
• て-form: よくて

So not いいて.

Yes. Both are nouns.

That is why the sentence is not using them like adjectives directly. Instead, Japanese uses a pattern like:

• 見晴らしがいい
• 風通しがいい

Literally, this is closer to:

• The view is good
• The ventilation is good

English often turns those into more natural phrases like:

• It has a good view
• It gets good airflow

So this is a very normal Japanese structure: noun + が / も + いい.

いい and よい both mean good.

• いい is the more common everyday spoken form
• よい can sound a bit more formal, written, or careful

So this sentence could also be:

• この部屋は見晴らしもよいし、風通しもよい。

That is correct, but it sounds stiffer.

One important thing learners should remember is that いい behaves irregularly in some forms because it comes from よい:

• よくて
• よくない
• よかった

But いい itself is perfectly normal in plain form, so いいし is natural.

It is plain style because it ends with いい rather than いいです.

Plain style does not automatically mean rude. It is just the non-polite form. It is common in:

• casual conversation
• dictionary examples
• written narration
• speech to friends or family

A polite version would be:

• この部屋は見晴らしもいいし、風通しもいいです。

That sounds more appropriate in polite conversation.

Often, yes.

That is one of the common nuances of 〜し. When someone says:

• 見晴らしもいいし、風通しもいい。

it can sound like:

• The view is good, the ventilation is good, and those are not the only nice things about it.

This is not a hard rule, and context matters, but 〜し often feels less final and more like I’m giving you some reasons/examples.

No. Normal Japanese writing does not usually put spaces between words like this.

It would normally be written as:

• この部屋は見晴らしもいいし、風通しもいい。

Learner materials sometimes add spaces to make the structure easier to see, but that is not standard everyday writing.

Yes. That is a very helpful literal breakdown.

A rough literal mapping is:

• この部屋は = as for this room
• 見晴らしもいいし = the view is good too, and...
• 風通しもいい = the ventilation is good too

That kind of literal reading is useful for understanding the grammar, even if a more natural English translation might be something like:

• This room has a good view and good ventilation.
