This place is absolute hell if you get lost so I'm going to try and help some of you dudes outs. Very minor spoilers about the area follow, more tips than anything.
When you first get to the area and roll onto the wood platform, run to the right avoiding holes, you'll see an item in to your left. Roll onto that platform and turn around, there's a bonfire in that direction. Don't fall off like I did, you'll want to die.
If you haven't been using torches up until this point. Use them. Seriously. Light everything up that you possibly can.
If you make it to a fog door that has a big ant looking thing in it, do a 180 and go into that building behind you, make your way to the back of the room, there's a bonfire behind a destructable wall.
I hope this at least helps one person out because fuck The Gutter.
