I used to use airbnb quite often (as a traveler), but I have to say it's lost its appeal for me. First, it's really not much cheaper than a hotel in most cases (some cases more expensive). Second, it's a hassle when you're on vacation to have to arrange in advance a specific time to pick up the keys to the place. Then, what happens if you happen to lose the keys (happened to me once)? What happens if it's in the middle of the night in a foreign country? This could be a nightmare. On top of that, you're expected to leave the apartment like you never stayed there or face bad reviews (even with a $100+ cleaning fee)! Seriously, one time I got stuck with a terrible review because I left a dirty pan in the sink (had to rush to the airport, I figured the $100 cleaning fee would cover what minor things I had left behind, but guess not).
