so, i've spent the better part of the last 2 hours researching. conclusion: airbnb is seriously the best.
look at these places for rent:
a houseboat in amsterdam for $140/night
this insanity in ireland for $168/night
a tugboat in sausalito, california for $150/night
this ridiculousness in portugal for $54/night (for the whole stinkin' place!)
the cutest apartment in paris for $275/night
a 5 bedroom villa in mijas, spain for $345
(split that between 5 people and it's basically free)
dying over here.
