Working with HouseTrip made my France trip very enjoyable. Because most stays were less than 2 days we only used HouseTrip for Paris and Lyon but both apartments were exactly as described and each hostess was very nice.
My only complaint about the whole process is when you reserve the apartment, the next steps are not entirely clear. You make one or more requests and apparently you are supposed to receive the contact information - but that didn't happen the way I thought it would.
However, once you figure out that little usability issue - the experience is great and I would highly recommend it!
