Chosen answer: Because of the stink and water, it would be impossible for police dogs to track him. The sewers are also good for quick retreat and hiding.
Answer: With how many criminals Frank has killed, many of them would definitely want revenge. By hiding in the sewers, there's less chance of him or his hideout being discovered. If Frank lived anywhere above ground, his enemies would be able to find him more quickly and kill him.
