Στο ξενοδοχείο ήταν όλοι εξυπηρετικοί, και το δωμάτιο είχε καθαρά σεντόνια και ωραίο άρωμα.

Στο is the contracted form of σε το, meaning in the or at the with a neuter singular noun.

• σε + το = στο
• στο ξενοδοχείο = in/at the hotel

This contraction is standard in normal Greek.

It is in the accusative case because it follows the preposition σε.

The basic noun is:

• το ξενοδοχείο = the hotel

After σε, the form stays the same here because many neuter nouns have identical nominative and accusative forms:

• το ξενοδοχείο
• στο ξενοδοχείο

So even though the form looks unchanged, grammatically it is accusative.

Both are in the imperfect past tense.

• ήταν = was / were
• είχε = had

The imperfect is often used for descriptions, background information, or ongoing states in the past. That fits this sentence well, because it describes what the hotel and room were like.

So this sounds like:

• the staff were helpful
• the room had clean sheets and a nice smell

rather than a one-time completed action.

Όλοι means all when referring to people, usually masculine or mixed-gender groups.

Here όλοι means something like:

• everyone
• they were all helpful

If the group were known to be all female, Greek would use όλες.

So:

• όλοι εξυπηρετικοί = all of them were helpful

It does not mean all things here. Όλα would be neuter plural and would refer to things, not people.

Because it agrees with όλοι.

Greek adjectives must agree with the noun or pronoun they describe in:

• gender
• number
• case

Here the understood group is plural, so the adjective is plural too:

• όλοι εξυπηρετικοί = all helpful / all of them were helpful

If you were talking about one man, it would be:

• εξυπηρετικός

For one woman:

• εξυπηρετική

Actually, ήταν already is were.

Greek word order is more flexible than English. The structure here is:

• Στο ξενοδοχείο ήταν όλοι εξυπηρετικοί
• literally: At the hotel were all helpful

But natural English is:

• Everyone at the hotel was helpful
• or At the hotel, everyone was helpful

So nothing is missing; Greek is just arranging the sentence differently.

Here καθαρά is an adjective, not an adverb.

It agrees with σεντόνια:

• σεντόνια = sheets, neuter plural
• καθαρά = clean, neuter plural

So:

• καθαρά σεντόνια = clean sheets

This can confuse English speakers because καθαρά can also look like an adverb in other contexts. But in this sentence it is clearly an adjective describing the noun.

Because άρωμα is a neuter singular noun.

The adjective ωραίος changes form to match the noun:

• masculine: ωραίος
• feminine: ωραία
• neuter: ωραίο

Since άρωμα is neuter singular, the correct form is:

• ωραίο άρωμα = a nice smell / a pleasant scent

Because Greek has no indefinite article equivalent to English a/an.

So Greek can simply say:

• είχε καθαρά σεντόνια = it had clean sheets
• και ωραίο άρωμα = and a nice smell

If Greek uses the definite article, it would sound more like the clean sheets or the nice smell, depending on context.

Here the nouns are indefinite/general, so no article is needed.

Because the room is one thing, while sheets are naturally plural.

• το δωμάτιο = the room
• σεντόνια = sheets

So the sentence says that the room had clean sheets. That is perfectly normal in both Greek and English.

Και means and.

In this sentence it connects two kinds of things:

1. Two clauses:

   • Στο ξενοδοχείο ήταν όλοι εξυπηρετικοί
   • το δωμάτιο είχε...

2. Two noun phrases inside the second clause:

   • καθαρά σεντόνια
   • ωραίο άρωμα

So Greek uses και just as flexibly as English and.

Because Greek often puts the setting or topic first.

Starting with Στο ξενοδοχείο gives a natural sense of:

• As for the hotel...
• At the hotel...

This is a very common Greek word-order choice. It helps frame the sentence before giving the comment about the people there.

Both versions are possible, but the original sounds natural and descriptive.

Yes, in context it effectively means everyone or they were all.

Greek often uses όλοι in a way that English might translate differently depending on style:

• ήταν όλοι εξυπηρετικοί
  • everyone was helpful
  • they were all helpful

So the exact English wording can vary, but the Greek meaning is the same.

Άρωμα usually sounds more pleasant and often more refined than μυρωδιά.

• άρωμα = fragrance, pleasant scent
• μυρωδιά = smell, odor, scent in a more general sense

So ωραίο άρωμα strongly suggests a nice, pleasant smell in the room. It is a good choice for a positive description.

Yes. Greek σε often covers both ideas, and English chooses in or at depending on context.

So:

• Στο ξενοδοχείο can be understood as
  • in the hotel
  • at the hotel

In this sentence, English might naturally say either:

• At the hotel, everyone was helpful
• In the hotel, everyone was helpful

Usually at the hotel sounds more idiomatic in English for the first part.
