Bạn có biết khách sạn nào sạch và rẻ không?

Bạn means you, but more specifically it is a common way to address someone in a friendly, fairly neutral way.

A few important points:

• It is very common in textbooks because it is simple and useful.
• In real life, Vietnamese often uses kinship-style pronouns instead, depending on age and relationship: anh, chị, em, cô, chú, bác, etc.
• So bạn is not rude, but it is not always the most natural choice in every situation.

In this sentence, bạn is perfectly understandable as a general you.

This is a very common Vietnamese way to make a yes/no question:

có ... không?

In this sentence:

• có biết = do/does ... know
• không? at the end turns it into a question

So:

• Bạn có biết ... không? = Do you know ...?

This pattern is extremely common in Vietnamese. You can think of it as the equivalent of using do/does in English yes/no questions.

Examples:

• Bạn có khỏe không? = Are you well?
• Bạn có thích cà phê không? = Do you like coffee?

Biết means to know.

When Vietnamese forms a yes/no question, it often places có before the verb and không at the end:

• Bạn biết khách sạn nào...? = You know which hotel...? / Do you know any hotel...?
  This can work in conversation.
• Bạn có biết khách sạn nào... không? = a very clear, standard yes/no question: Do you know any hotel...?

So có is not changing the core meaning of biết. It is helping form the question pattern.

Here nào means something like which or any, depending on context.

So:

• khách sạn nào = which hotel / any hotel

In this sentence, the natural English meaning is any hotel:

• Bạn có biết khách sạn nào sạch và rẻ không?
• Do you know any hotel that is clean and cheap?

Why not always translate it as which? Because English uses different wording depending on context. Vietnamese nào can cover both ideas.

In Vietnamese, descriptive words often come after the noun, especially in structures like this.

So:

• khách sạn sạch = clean hotel
• khách sạn rẻ = cheap hotel
• khách sạn nào sạch và rẻ = a hotel that is clean and cheap

English usually puts adjectives before the noun:

• a clean, cheap hotel

Vietnamese often puts the description after the noun:

• khách sạn sạch và rẻ

So the word order is different from English, but very normal in Vietnamese.

Vietnamese often leaves out words that English requires.

In English, we say:

• a hotel that is clean and cheap

In Vietnamese, you can simply say:

• khách sạn nào sạch và rẻ

There is no need for a separate word meaning that is here. The description follows the noun directly, and the meaning is understood naturally.

This is very common in Vietnamese.

Functionally, it is describing the hotel: clean and cheap.

You can think of it as shorthand for:

• khách sạn nào mà sạch và rẻ
• roughly: any hotel that is clean and cheap

In everyday Vietnamese, the shorter version is more natural here:

• khách sạn nào sạch và rẻ

So while it may feel incomplete from an English perspective, in Vietnamese it works perfectly as a noun phrase with a following description.

Yes, you can.

Both are natural:

• Bạn có biết khách sạn nào sạch và rẻ không?
• Bạn biết khách sạn nào sạch và rẻ không?

The version with có ... không is a very clear textbook-style yes/no question pattern.

The version without có is also common in speech and sounds a bit lighter or more conversational in some contexts.

So both are good, but the full có ... không pattern is especially useful for learners.

Not really, at least not word-for-word in natural English.

By itself, không often means not or no. But in the pattern có ... không?, it helps form a question.

So in this sentence:

• không is not simply negating the sentence
• it is part of the question structure

That is why the whole sentence means:

• Do you know any clean and cheap hotel?
• not You do know any clean and cheap hotel not

It is better to understand the whole pattern instead of translating không alone.

Và means and.

So:

• sạch và rẻ = clean and cheap

You need some connector if you want to clearly join the two qualities. In casual speech, Vietnamese sometimes lists adjectives without và, depending on rhythm and context, but và is the clearest standard form here.

So for learners, sạch và rẻ is the best version to use.

It is asking for any hotel that fits those qualities.

Because of khách sạn nào, the speaker is not asking about one already-known hotel. They are asking whether the listener knows some hotel / any hotel that is:

• sạch = clean
• rẻ = cheap

So the sense is closer to:

• Do you know any clean and cheap hotel?
• Can you recommend a hotel that is clean and cheap?

Not necessarily.

English often needs an article like a:

• a hotel

Vietnamese does not require that in the same way.

So:

• khách sạn nào already works well as any hotel / which hotel
• adding một is usually unnecessary here

A sentence like Bạn có biết một khách sạn nào sạch và rẻ không? sounds awkward. The natural version is the original one.

A useful breakdown is:

• Bạn = you
• có biết = do know / know
• khách sạn nào = any hotel / which hotel
• sạch và rẻ = clean and cheap
• không? = question marker in the có ... không pattern

So the structure is roughly:

You + do know + any hotel + clean and cheap + question?

In smoother English: Do you know any hotel that is clean and cheap?

This is a good example of how Vietnamese often keeps the meaning clear while using word order and grammar that differ from English.
