Spend some money on a decorator who understands the style to help choose colors, etc. 

Decorate it if you want to.....

I have many tenants that after seeing their decor, clothes they where, etc that I know we have a lot in commmon and could probably be friends, but I would never.

Unfortunately I cannot afford major renovations at the moment but I do plan on investing in nice decorations.

My only idea; "close it off" in a way that makes it Look like there is a full masonry lined block, when in reality it is just a piece of plywood with a sheet of concrete backer board over it... or something similarly easy to remove when the time comes to sell.Then tell them that it's fully closed and unusable to avoid any issues :D maybe you could even put some sort of decoration or fake fireplace setup to make it look nice?

I bought furniture and amenities and decorated, then listed on Airbnb What was the outcome?

And they all match.You can't ask the tenant to pay the price for what is a less-than-optimal decorating choice. $200 blinds (plus installation) do not belong in any sort of rental property, of any class.

If you go more medium term you  would not go overboard on decor and selling the area.

I am curious about decorations.
