Earlier quoted context omitted.
I came to Athens last summer and spent 4 nights in the city staying in an AirBnB style rent. I thought it would be better doing this than giving my money to a generic international hotel chain but you disagree apparently. I find your solution unworkable personally. When I travel I like to have somewhere private I can come back to after a long day, the coach surfing model doesn't appeal to couples.
Unfortunately, most of the owners of Airbnb and other short-term rentals in Greece are non-Greek citizens who got a "golden passport" in the recent years, buying off a huge chunk of the apartment inventory in Athens and elsewhere. Re: couch-surfing -- probably a bad metaphor on my end. I meant the "rent a room in a house" model that Airbnb offers.
Cool city but some worrying experiences, might check out some islands next time.
