This will primarily effect tenant's sales and your ability to re-lease when tenant moves out.You have building risk: primarily, how easy will it be to re-tenant if your tenant goes dark or leaves.  

If you are trying to maximize space you may want to consider convertible sofas and/or one that has a pull out option.As far as material my preference would be a darker neutral color microfiber that would be easier to clean.Possibly most important is looking for one that is commercial grade for durability.

I find this to look spammy and over-promotional.Use a lot of blue and green, as those colors signal trust and comfort.

I agree 100% that most investors spend too much time on the fun stuff, looking at 'deals', building models, picking paint colors and don't spend enough time in self reflection to understand what the are and aren't good at.

I usually adjust temperature right before a check in to make it comfortable for guest.Love the Honeywell 9000 color touchscreen thermostats.They also allow me to locking a temperature range so the guests can't set temperature to 60 in the summer.

Things start to get really dark of ya wear that thing too long, lol. 

Jay told me many years ago when I lost his money on a deal “A man shows his true colors in times of adversity and not triumph”I agree with Jay on his opinion here as he doesn’t have a dog in the fight.We both met Marco and he always seemed like a decent fellow.Time will reveal all but nuking the fella doesn’t get anyone their cheese back.Just my opinion  

Should I stain these doors and hardwood floors a dark expresso color, or lighten them, or just leave them alone?

You're gonna need to provide more color here.
