"Innocence, my brother."
After the doors start you up, you already know that Cicero is wounded, so you will find him by blood stains. There may be traps to avoid. Meet the Guardians there.
Come inside, go straight. Stop in front of the door leading forward. Look left and find a set of bathrobes on the table. Go north and open the door. There are keepers.
When you're done with them, go inside and turn left. Keeper in front of you, talk to him. Move forward. Turn west. Near the bridge you need to stop. Watch out for traps and the Guardian.
Go through the bridge, go down the stairs. Below you will find books. Drive carefully under the bridge. There are a couple of Keepers and a trap. Go down the corridor, exit through the broken window. Follow the traces of blood, then go down the corridor to the right. This will allow you to kill the troll. After that, go down to the ground level, find a trace of blood, go forward.
Open the wooden door and go to the right side of the gate. Pull the chain to lower the bars blocking the path forward. After that, step onto the stairs. Go through the passage below.
Go forward, climb the stairs at the end of the corridor. On the right you will find a chain to lower the rods. Go to the end of the corridor forward, to the right you will find the next door, open.
You will see Cicero curled up and badly hurt. You can kill him or leave him alive.
When you return to the Dark Brotherhood, find Astrid. Talk to her to complete the quest. Lie to her if Cicero is alive, or say that you killed him.
Many players keep him alive as the buffoon is a pretty fun companion. For no reason, he can begin to dance and sing, laugh and have fun, not paying attention to what is happening around. You can use it to kill opponents. He has excellent health, good magic, a supply of strength, secrecy. Therefore, they often choose it as a satellite.
And finally, the advice: if you still decide to leave Cicero as a companion, do not give him a heavy shell, because this is irrational.
