When I moved it I had electricity (which I barely used except to run appliances, and I mean that my monthly bill averaged $30), heat (which again I barely used...nothing that cheap sweatshirts and blankets can't fix if you're just sitting on your computer looking at BP), and running water...and in this regard I literally mean running because I had a 4 foot hole in my dining room ceiling with a plumbing leak and a red Solo cup to catch the drip while I slept on an air mattress on the floor.

Ie. he turned in the key so I considered him gone and thought he abandoned the ratty old couch and mattress that are still there?

Mattresses, linens, towels, kitchen stuff (for the most part) were all new.Now I will say I am a deal finder and am still finding great stuff to furnish a house.

Yellow stains are everywhere on mattresses and pillows\ inserts that probably will stop 90% of travelers from sleeping there.

what I really hate during Airbnb stay:- bad mattress- no charger- internet doesnt work- no cable TV - cockroach - no pillow ?

In my experience with guests remaking the bed, they're never making it as neatly as my housekeeper (probably not tucking sheets in under the mattress, arranging pillows the same way, etc) so while at a glance it might look the same, closer examination will probably reveal if it's been used.  

, stuff it in a mattress?

Charge less and give them a bring your own air mattress special.  

Buy reasonable beds and then use Groupon to buy memory foam toppers.

Hey Daniel - welcome we fund deals with mattress money  in laymen terms - what is crowdfundingis crowd funding - when everybody pitches in to get a keg of beer??
