Lol. It's quite funny, I've had to ask for directions in FFXIV. Just shows how huge the game is.
I do agree, there's very little actual information on what is where. I even had trouble finding an NPC that another NPC said was on the lower decks (in LL.) That is how bad I am with directions.
So I usually have to use YG. It's got a FFXIV database of a variety of things. (Including NPCs). I can suggest it to anyone else that is easily lost and has difficulty finding things.

YG: FFXIV Database

I know quite a few people were using this website when there was no item search for the wards. Also has a list of players with bazaars. (If they are a member of the website and have updated their bazaar list). Pain in the behind. But works. Usually.
