I recently moved into an apartment and there is a strange smell in one of the bedrooms. It isn't a horrible smell, but it's noticeable when you walk in and then you get used to it real quickly. Before anything was moved in, there was no sign of mold or any obvious causes. It's also the only room of the apartment with hardwood floors and they weren't treated very well. I've scrubbed the floor with Murphy's oil soap diluted in hot water, and nothing seems to have changed. Also worth mentioning that the apartment is in a house that's a bit older.
Any ideas? Sorry I can't describe it any better than that, it's just a hard smell to put a name on.
