Learn French: Pour l'hébergement, lequel est le plus confortable ? - For the accommodation, which one is the most comfortable?

Lequel translates to "which one" and must agree in gender and number with the noun it replaces. Here, it refers to l'hébergement (the accommodation), which is a masculine singular noun. If we were talking about a feminine noun like la chambre (the room), we would use laquelle.

Could I say Lequel hébergement est le plus confortable ?

No, because lequel is a pronoun, meaning it stands in for the noun entirely (just like "which one" in English). If you want to keep the noun right next to the question word, you must use the adjective quel instead, making it Quel hébergement est le plus confortable ?

How do we know l'hébergement is masculine if it starts with l'?

Words starting with a vowel take l' whether they are masculine or feminine, which can hide their gender. However, the rest of this sentence gives it away! Both the pronoun lequel and the article le in le plus confortable are masculine singular, proving that hébergement is masculine.

Why is there a le in front of plus confortable?
