Hidden Bathroom

So there was a room in my house that was locked, just off my bedroom. I decided to try all my keys on it to see what it was and, lo and behold, I found a bathroom! They had told me the room was unfinished and that's why I couldn't open the door. Clearly not the case. It was, however, completely dirty and disgusting. But no longer! Now it's a lovely bathroom. Yay! Still no running water, but that's just par for the course here in Guinea.
