Need advice to make this interior more appealing

[Sam Leon]

I need to do something to a property where a portion of a property was extensively redone by the previous owner with a VERY different taste then mine, and that fits his lifestyle at the time.  Now that I am about to rent it out, I wanted something that is appealing to as many people as possible.

Property is located in South Florida in a class B neighborhood.  It is a duplex with each unit about 1200SF.  Unit B is fine but unit A was the one lived in by the previous owner.

About 400SF of space, which included the entrance foyer and the kitchen, requires some "tweaking".

The owner has lined the walls from floor to ceiling with dark wood panels with some elaborate trims.

To the right, you can see a bar.  The bar has already been removed.

The floor is the same wood, in laid with stone tiles.

But the ceiling is the main issue.  The ceiling is broken into multiple "trays" with each tray about 3.5' X 3.5'.  There is a mirror glued onto the ceiling in each tray, then wood trim all around.  In the middle of the each mirrored tray is a 6" recessed light.

I have had a few friends came by to visit while I was doing a bunch of repairs and the comments I got as soon as they stepped into this area were:

"wow...man cave"

"speakeasy?"

"was this once a brothel?"

"this guy was into some funny business...you may find drugs hidden behind walls or in the attic..."

...and the mirrored ceiling got the most attention.

Oh, there was also a seven foot long aquarium in the same wood trim dividing the foyer and the kitchen but that was removed.

I have considered removing the ceiling and just go back to regular sheetrock.  But this would be VERY laborious and expensive.  There are all together 24 of these ceiling trays.

If I can removed the wood trims - don't think this is going to be too difficult, the glued on mirrors would be a real pain to remove.  Not only that, there are custom cabinetry in the kitchen that is very close to the ceiling, that would make the removal of the trims and mirrors very difficult, unless I remove those cabinets too.

I am leaning towards keeping the walls and floors but change the ceiling.

Any thoughts as to what I can do to the ceiling that would make it appealing to most renters?

Is ripping everything down the only option?

Or are there creative alternatives?
