De momento, a mi hermana le vienen bien los festivales pequeños, porque no le gustan las salas llenas.

De momento means for now, at the moment, or for the time being. It shows that this is the situation right now, but it may change later.

So in this sentence, it suggests that her preference for small festivals is temporary or current, not necessarily permanent.

A close alternative is por ahora.

Spanish often uses double marking with indirect objects:

• a mi hermana = to my sister
• le = to her

Even though both refer to the same person, this is normal Spanish. The pronoun le is usually required, and a mi hermana adds clarity or emphasis.

So a mi hermana le vienen bien... is a very natural structure.

Venir bien is a very common expression meaning:

• to suit someone
• to be good for someone
• to work well for someone
• to be convenient for someone

So a mi hermana le vienen bien los festivales pequeños means that small festivals are a good fit for her / suit her well.

It does not literally mean come well in English, even though that is the literal translation of the words.

Because the subject is los festivales pequeños, which is plural.

In venir bien, the thing that suits someone is the grammatical subject:

• El festival pequeño le viene bien = The small festival suits her
• Los festivales pequeños le vienen bien = Small festivals suit her

So the verb agrees with festivales, not with mi hermana.

For the same reason: las salas llenas is plural, so the verb must also be plural.

With gustar, the thing that is liked or disliked is the grammatical subject:

• Le gusta la sala llena = She likes / doesn’t mind the full venue
• Le gustan las salas llenas = She likes full venues

Here it is negative:

• no le gustan las salas llenas = she doesn’t like full venues

So gustan agrees with las salas llenas.

Gustar works differently from English to like.

In Spanish, the structure is closer to:

• las salas llenas = full venues
• le gustan = are pleasing to her

So no le gustan las salas llenas literally works like: Full venues are not pleasing to her.

That is why le means to her, and why the verb agrees with salas llenas, not with ella.

In Spanish, adjectives usually come after the noun:

• festivales pequeños
• salas llenas

That is the normal order.

If an adjective comes before the noun, it often adds a more subjective, stylistic, or emotional nuance. In this sentence, there is no special effect needed, so the standard order is used.

Not exactly. Sala can mean room, but in this context, especially in Spain, it often means a venue, hall, or concert space.

So las salas llenas means something like:

• full venues
• packed halls
• crowded indoor spaces

Because the sentence talks about festivals, salas is best understood as performance spaces or venues, not just ordinary rooms in a house.

Because llenas describes salas, and adjectives must agree in gender and number with the noun they describe.

• sala = feminine singular
• salas = feminine plural
• therefore: llenas = feminine plural

Compare:

• la sala llena
• las salas llenas
• el festival pequeño
• los festivales pequeños

Yes, it can, if the context already makes it clear who le refers to.

You could say:

• De momento, le vienen bien los festivales pequeños...

But adding a mi hermana makes it clear and sounds more natural if you are introducing the person or contrasting her with someone else.

So:

• A mi hermana le... = clearer / possibly more emphatic
• Le... = possible when the context already tells us who it is

Not quite.

• de momento = for now / for the time being
• en este momento = at this exact moment right now

In this sentence, de momento is better because it refers to a current situation or preference, not to one exact instant in time.

So de momento suggests: Right now, this is what suits her.

Yes, that is a very natural translation.

Literally, salas llenas means full halls/venues, but in natural English, crowded venues or packed venues often sounds better.

That is a good example of how a natural translation may be better than a word-for-word one.

Yes, it sounds very natural in Spain, especially because of the word salas for music or event venues. That usage is very common in Spain.

The grammar itself is standard Spanish everywhere, but some vocabulary choices, like salas, may feel especially familiar in Peninsular Spanish contexts.
