So I contacted both Lodgis and ParisAttitude (PA)and I had positive experience with both of them but ended up going with ParisAttitude simply because they had the listing I wanted. PA seems to charge higher commissions but in the end the rent I pay is much less than if I had used Airbnb for a comparable apartment. But at the same time, its a bit more work (with Airbnb, you are done after a few clicks) but with PA (and Lodgis), you have to send your financial docs to make the French landlord feel comfortable (eg if you don't have a regular pay slip, you have to get a guarantor from a company like Garantme or just pay everything upfront). My only concern with PA is that they have a lot of negative reviews on YELP about how the landlords do not return the 2 month security deposit (or take a long time) and PA doesn't do much to assist ....but I can't worry about that now and I have to trust that at the end of my stay my new landlord will be fair and honest. For now, I'm just relieved that I found something decent for my family in Paris. Merci beaucoup Ă tous!
