I drop by to store outfits I like but don't intend to wear beyond a few photomode ops when I'm just goofing around. Reaching the apartment takes way too much time IMO. It would be fine if there was a lot of interaction with the neighbors on the way or some reasons we'd want to walk through the building, but after you've exhausted a few of the little quests in the area, there isn't much reason to be there.
Apparently I'm overdue on rent, but there's no way I can find to pay it. Is there another place you can access your stash from? The game mentioned there was, but I haven't found out. I feel like I'm missing something obvious, but there's a lot of features missing that obviously should have been included... so I never really know.
