Another Beginner's Grammar Question

[improperlyhuman]

I'm totally new to Russian grammar, so I want to know if my thinking process is incorrect.

My sentence is

Вечером я пишу в своей гостиной.

I guessed from the ending of гостиная that it is feminine, and в is a preposition, although not expressing motion. So, I looked at the endings for singular feminine nouns in the prepositional case. -ой is not listed on my chart. I also have Schaum's Russian Grammar, and it's not there either. I don't understand this noun suffix.

Thanks

Off-topic, but the phrase itself sounds a bit strange for a native speaker. It's not completely wrong, for instance, I can imagine it in a letter, but not in a conversation. The problem is that "пишу" is a simple present of imperfect verb. It can be used for the current moment ("I am writing my comment right now"), some repeating activity ("I write into my journal every day") or even in the known future ("This night I write an essay"), but the adverb "вечером" doesn't fit well into any of these cases.

- По вечерам я пишу в своей гостиной.
- Сегодня вечером я пишу в своей гостиной.
