We live in Europe and prefer using housetrip. It's based here and seems less dodgy/tacky and has what seems to be very close in number listings. I believe they were around before airbnb, although I'm not sure. I know I was using then before I heard about airbnb.
I'm also European, and I had never heard of them. On first impression, it looks like an AirBnB clone lacking in polish (eg. no hybrid list/map view; detected my language, but showed me prices in GBP, etc).
