"un" on not?

Question

Is the following example correct, as I want to add an "un"?

"Se vende apartamento de lujo en la playa. A luxurious apartment is for sale at the beach."

A luxurious apartment is for sale at the beach."

Hola Jessica H.
In Spanish, when using the "se vende" (pasiva refleja) structure, it’s very common to omit the article "un/una", especially in advertisements or signs. So:
"Se vende apartamento de lujo en la playa"
is perfectly correct and natural. It’s how you'd often see it in real-life contexts like real estate ads.
However, you can also say:
"Se vende un apartamento de lujo en la playa",
which is equally correct grammatically. This version simply sounds a bit more specific, as if you're referring to one particular apartment rather than making a general statement.
So, both are valid! The choice depends slightly on tone and context, but your original sentence works perfectly as is.
Hope this helps!
Un saludo
