kèfáng lǐ yǒu zhèxiē shèshī.

Chinese often uses the pattern:

place + 里/上/etc. + 有 + thing

This is the standard way to say that something exists in a place.

So:

• 客房里 = in the guest room
• 有 = there is / there are / has
• 这些设施 = these facilities

So 客房里有这些设施 literally follows the Chinese existential pattern:

In the guest room, there are these facilities.

You can also say 这些设施在客房里, but that shifts the focus. It means more like:

These facilities are in the guest room.

So the original sentence is more natural when introducing what is available in that place.

里 means inside or in.

In 客房里:

• 客房 = guest room
• 里 = inside

So 客房里 means in the guest room.

It is a location word, similar to inside in English, though in Chinese it is used much more naturally after nouns to mark location.

Sometimes yes, but the meaning or feel can change a little.

• 客房里有这些设施 = There are these facilities in the guest room
• 客房有这些设施 = The guest room has these facilities / Guest rooms have these facilities

With 里, the sentence clearly treats 客房 as a location.

Without 里, 客房 sounds more like the subject or topic that possesses the facilities.

So both can work, but 客房里有这些设施 is especially natural if you want to emphasize the location.

Yes, 有 often means to have, but it also has an existential use meaning:

there is / there are

In this sentence, 有 does not just mean possession in the English sense. It means that something exists in a place.

A very common Chinese pattern is:

A place + 有 + something

For example:

• 桌子上有一本书。 = There is a book on the table.
• 房间里有两个人。 = There are two people in the room.

So in 客房里有这些设施, 有 means there are.

这 means this, while 这些 means these.

Since 设施 refers to more than one facility, 这些 is used.

Compare:

• 这个设施 = this facility
• 这些设施 = these facilities

So 这些 is the plural demonstrative form.

Because 些 already works as a kind of plural marker here.

In Chinese:

• 这 = this
• 这个 = this one / this item
• 这些 = these

When you use 这些, you do not add another classifier after it.

So:

• 这些设施 = these facilities

Not:

• 这些个设施 in standard careful usage here

So 这些 already does the job of indicating more than one.

By itself, 设施 can be understood as a general noun meaning facilities or facility/facilities, depending on context.

Chinese nouns usually do not change form for singular vs. plural the way English nouns do.

So:

• 设施 can refer to facility/facilities in a general sense
• 这些设施 clearly means these facilities

In this sentence, the plural meaning is clear because of 这些.

客房 usually means a guest room, especially in places like:

• hotels
• guesthouses
• homes with rooms for guests

It does not usually mean just any room.

For comparison:

• 房间 = room
• 卧室 = bedroom
• 客房 = guest room

So in this sentence, it most likely refers to a hotel guest room or similar accommodation.

Usually, that sounds less natural in standard Mandarin.

With existential 有, the location usually comes directly before 有 without 在:

• 客房里有这些设施。 ✔
• 在客房里有这些设施。 less natural in a simple statement

Chinese often prefers:

location + 有 + noun

rather than:

在 + location + 有 + noun

You may sometimes hear 在...里有... in longer or more special sentence structures, but for a basic sentence like this, 客房里有这些设施 is the most natural choice.

这些 is pronounced zhèxiē.

• 这 = fourth tone
• 些 = first tone

So it is:

• zhè (falling tone)
• xiē (high level tone)

There is nothing especially irregular here; just remember that 这 keeps its fourth tone.

The pinyin is:

Kèfáng lǐ yǒu zhèxiē shèshī.

Tone by tone:

• 客 kè — 4th tone
• 房 fáng — 2nd tone
• 里 lǐ — 3rd tone
• 有 yǒu — 3rd tone
• 这 zhè — 4th tone
• 些 xiē — 1st tone
• 设 shè — 4th tone
• 施 shī — 1st tone

A natural rhythm is:

Kèfáng lǐ | yǒu zhèxiē shèshī.

You can think of 客房里 as one chunk and 有这些设施 as another.

The easiest way is to add 吗 at the end:

客房里有这些设施吗？
= Are there these facilities in the guest room?

You can also ask more naturally in conversation with 有没有:

客房里有没有这些设施？
= Does the guest room have these facilities?

Both are correct, but 有没有 is very common in spoken Chinese.

To negate 有, you use 没有, not 不有.

So:

客房里没有这些设施。
= There are not these facilities in the guest room.
More naturally: The guest room does not have these facilities.

This is an important point because 有 is one of the verbs that is normally negated with 没(有).

It depends on context.

客房 by itself does not show singular/plural clearly. Chinese often leaves that to context.

So 客房里有这些设施 could mean:

• There are these facilities in the guest room
• Guest rooms have these facilities

If the speaker is describing a specific room, it sounds singular.
If the speaker is talking about hotel amenities in general, it can sound more general.

Chinese often relies on context where English would force you to choose between singular and plural.
