Here, -에서 marks the starting place or source of the movement.

So 회의실에서 나와서 means coming out from the conference room.

Learners often first meet -에서 as at/in with actions, as in 학교에서 공부해요. But with verbs like 나오다, it can also mean from.

Because 나와서 is the contracted form of:

나오다 + -아서 → 나와서

This happens because 오 + 아 usually contracts to 와.

A similar pattern appears in:

• 오다 → 와요
• 보다 → 봐요

So 나와서 is the normal, natural form.

In this sentence, -아서/-어서 connects two actions in sequence.

So the sense is:

come out of the conference room, and then go down ...

It is not really expressing because here. It is showing that one action happens first, followed by the next one.

The order matters:

1. 회의실에서 나와서
2. 계단으로 내려가요

Both verbs relate to leaving, but they are not exactly the same.

• 나오다 = come out
• 나가다 = go out

With enclosed places like rooms or buildings, 나오다 is very common when talking about emerging from inside to outside or into the surrounding space.

So 회의실에서 나와서 feels like come out of the conference room.

If you used 나가다, the feeling would be more like simply go out. In real Korean, both can appear depending on viewpoint and nuance, but 나오다 is very natural here.

Here -으로 is best understood as marking the route or means.

So 계단으로 내려가요 can mean something like:

• go down by way of the stairs
• go downstairs using the stairs
• sometimes simply go down the stairs, depending on context

This is slightly different from 계단을 내려가요, which more directly treats the stairs as the thing being gone down.

A useful contrast is:

• 엘리베이터로 내려가요 = go down by elevator
• 계단으로 내려가요 = go down by stairs

So -으로 here has a strong via / using feeling.

This is the usual 가다 vs 오다 distinction:

• 가다 = go
• 오다 = come

So:

• 내려가요 = go down
• 내려와요 = come down

The sentence is describing movement away from the current point of reference, so 내려가요 is the natural choice.

If the speaker were located below, or if the movement were toward the speaker’s reference point, 내려와요 might be used instead.

The form 내려가요 is the polite present style, but Korean present tense often covers more than just a strict present-time meaning.

It can be used for:

• habitual actions
• step-by-step directions
• near-future actions
• general descriptions of a route or procedure

So in context, this could sound like:

• a neutral description
• an instruction
• part of giving directions

The -요 ending just makes it polite.

The subject is omitted because Korean often leaves it out when it is already clear from context.

Depending on the situation, it could mean:

• I come out of the conference room and go down the stairs
• we come out ...
• you come out ... in directions or instructions

This kind of omission is extremely common in Korean.

Yes, that is also possible.

With motion verbs, Korean sometimes uses:

• -에서 to mark the starting place or source
• -을/를 to mark the place being passed through or left

So both of these can be heard:

• 회의실에서 나와서
• 회의실을 나와서

In this sentence, 회의실에서 emphasizes from the conference room a bit more clearly. For a learner, that is a very straightforward and natural way to understand it.

Yes, that is normal Korean word order.

Korean usually places location, direction, and other context information before the verb. The main verb tends to come at the end of each clause.

So the pattern is:

• 회의실에서 = from the conference room
• 나와서 = come out and then
• 계단으로 = by way of the stairs
• 내려가요 = go down

This is one reason Korean can feel backwards compared with English, but it is completely standard.
