yahari eki made aruite gohun no heya ha ninki ga aru you desu.

やはり means something like:

• as expected
• after all
• just as I thought

It adds the feeling that the speaker is not surprised by the fact. In this sentence, it suggests:

• rooms that are only five minutes from the station on foot are popular, which is pretty much what you’d expect.

A very common casual equivalent is やっぱり.

This part literally breaks down like this:

• 駅まで = to the station
• 歩いて = walking / by walking
• 五分 = five minutes

So the idea is:

• five minutes to the station if you walk
• more naturally in English: five minutes on foot to the station

Japanese often builds time/distance expressions this way.

So:

• 駅まで歩いて五分の部屋 = a room that is five minutes from the station on foot

The て-form in 歩いて is functioning adverbially here, giving the means:
by walking.

まで means up to, until, or as far as. Here it marks the endpoint:

• 駅まで = up to the station / to the station

In this sentence, it tells you the destination used to measure the walking time.

So:

• 駅まで歩いて五分 = it takes five minutes to walk to the station

The の connects the whole phrase before it to the noun 部屋.

So:

• 駅まで歩いて五分 = five minutes on foot to the station
• 駅まで歩いて五分の部屋 = a room that is five minutes on foot from the station

You can think of の here as turning that time/location description into something that modifies 部屋.

In English we might say:

• a five-minute-walk-from-the-station room
• more naturally: a room that’s a five-minute walk from the station

Yes, basically. Japanese modifies nouns by putting the descriptive material before the noun.

English uses things like:

• a room that is five minutes from the station
• a room which takes five minutes to reach on foot from the station

Japanese does not need that, which, or who. It simply places the modifier before the noun:

• 駅まで歩いて五分の部屋

So yes, it functions similarly to a relative clause, even though the structure is different from English.

Because 人気がある is a very common set expression meaning:

• to be popular
• literally, something like to have popularity

So:

• 人気がある = is popular

That is the normal way to say it.

Particle roles here

• 部屋は = as for rooms... (topic)
• 人気がある = are popular / have popularity

So the sentence is structured like:

• As for rooms that are a five-minute walk from the station, they seem to be popular.

Using 人気です is generally not the standard way to express popular in this kind of sentence.

They are doing different jobs.

は

は marks the topic:

• 駅まで歩いて五分の部屋は = as for rooms that are five minutes from the station on foot...

が

が is part of the expression 人気がある:

• 人気がある = to be popular

So this is not a contradiction. It is very common in Japanese to have:

• topic marked by は
• something inside the predicate marked by が

A literal structure would be:

• As for five-minutes-on-foot-from-the-station rooms, popularity exists.

Natural English:

• Rooms that are a five-minute walk from the station seem to be popular.

Here ようです means:

• it seems
• it appears
• apparently

It softens the statement and makes it less direct or absolute.

So:

• 人気があるようです = seem to be popular = appear to be popular

This often suggests the speaker is judging based on some evidence, information, or general impression rather than stating it as a hard fact.

For example, maybe they noticed:

• those rooms get rented quickly
• listings disappear fast
• people often ask about them

Then ようです fits well.

Not exactly.

They can sometimes feel similar in translation, but they are different.

ようです

Usually means:

• it seems
• it appears
• based on evidence, observation, or reasoning

そうです (hearsay)

Means:

• I heard that...
• they say that...

So:

• 人気があるようです
  = It seems they’re popular.
• 人気があるそうです
  = I heard they’re popular.

In your sentence, ようです suggests an impression or conclusion, not just repeated information.

Both can express on foot, but they sound a little different.

歩いて

Literally walking

• very natural
• plain and everyday
• often used in these time/distance expressions

徒歩で

Literally by foot

• more formal or written-sounding
• common in ads, listings, maps, and real-estate descriptions

So you might also see:

• 駅まで徒歩五分の部屋
• 駅まで徒歩で五分の部屋

These are very natural too, especially in housing ads.

Your sentence with 歩いて五分 sounds a bit more conversational.

Here it is pronounced ごふん.

So:

• 五分 = ごふん = five minutes

This is worth paying attention to because 分 can be read differently depending on the number:

• 一分 = いっぷん
• 三分 = さんぷん
• 五分 = ごふん
• 十分 = じゅっぷん / じっぷん

So this is one of those common pronunciation patterns that learners just have to get used to.

In Japanese, nouns usually do not show singular vs. plural clearly unless the context makes it necessary.

So 部屋 can mean:

• a room
• rooms

In this sentence, it is best understood generically:

• rooms that are a five-minute walk from the station

So even though English may use a plural, Japanese does not need a plural ending.

Yes, it is natural. It sounds polite and fairly standard.

Tone-wise:

• やはり gives it a slightly thoughtful or observational tone
• ようです makes it softer and less blunt
• です makes it polite

So it sounds like something you might hear in:

• conversation
• a real-estate discussion
• an explanation about housing trends

A slightly more ad-like version might use 徒歩:

• やはり駅まで徒歩五分の部屋は人気があるようです。

But your original sentence is completely natural.
