Is that unreasonable?

From reading it also appears that even forbidding to drill holes for the cable seems to be illegal, since it would "unreasonably delay or prevent installation".Maybe you can start by simply forbidding a CenturyLink service, you will do your tenant a favor :) Sorry, recent bad experience.

The idea here is that the tenant is not unreasonably enriching the Landlord. 

Not unreasonably disturb the peace and quiet of other Tenants or neighbors.G.

If you think it is unreasonable, tell her exactly that.

They are 4 adults and 4 kids.Their reason for not taking me up on my offer to let them stay somewhere else is that they said its unreasonable to find last minute accommodations and the cost was prohibitive.They're claiming false advertising (due to the omission) and the guy with a bad back got zero sleep and his dream vacation was ruined.

Complainers can also be unreasonable. ) Don't become a go between. 

If in your gut you feel like they are being unreasonable don't ignore the red flags.  

Don't be afraid to say "no" if she is asking for something unreasonable.

They may have very reasonable goals and desires, or they may be totally unreasonable and unprepared to invest in an illiquid investment like real estate.
