I personally love living in a big urban area and enjoying all of the attributes of it(walkability, mass transit, culture, diversity, incredible restaurant and nightlife options, architecture, pro sports, entertainment), but I realize that's not for everyone.  

I'm going to follow this discussion as this guy is sure to be entertaining. 

Quality furnishings and a decent/modern entertainment set up as you mentioned with high speed internet for streaming movies (night time or for rainy days) makes for an enjoyable experience, and maybe a game system.

For a little extra entertainment or other wise why not join them one evening, because you may like it.

I think you are over-reacting or just being entertaining. 

As long as a request is logical and makes common sense, I entertain it. 

Maybe a 50k home I would entertain letting my tenants self-manage, but not in this case for obvious reasons. 

As long as they have jobs in place, good credit and rental history I wouldn't even entertain the rest of the applicants unless the first applicants back out.

By entertaining Tenant C in such a way on this issue you are creating an environment where they think you can control and fix any issue that comes up with other people.

Don't oblige them or even act like you're entertaining all their requests and make it clear that you've provided a nice, functional home and it will stay as-is.
