Cleaning services question

Hey i had a question about hiring cleaning services.

A few of our neighbors who cleaned their own place say that they regret it and have told us to hire someone.

We don’t have any fire damage but obviously have a lot of soot and ash to clean off of every surface. Does anyone have any recommendations for cleaning services? Would a service like Kleen or TaskRabbit be enough since we don’t have fire damage? Or do we truly need a professional deep cleaning?

If so, do you have any recommendations? We live in a small back house so it shouldn’t be too big of a job.

Lastly, does anyone know if landlords are responsible for cleaning/costs? I googled it and got conflicting answers. We have renters insurance but a lot of people we called for cleaning quotes mentioned that the landlord typically pays for this even if we have renters insurance.
