Airbnb - is a popular now flat booking ( all over the world), anyhow they have some problems with local TVA but they are still the worldwide giant of flats. They won the market with beautiful flat photos and the diversity of variants. Sometimes of course for economy of time its better to visit the Airbnb website for more options but you have to know that during the booking of the flat you have to pay some fees like cleaning, fee of cancelation and sometimes the flat will be far from your expectations. With private searching nobody gives to you garanties ( about he flat and lord holder) but the good point you may discuss the price and the terms of paiement.
