Absolutely great. It is clear that Nadji is very aware of a traveller's needs. The app is small (as all in Paris) but very well equiped and confortable. Everything is brand new and clean and beautiful, with all those small details everybody wants to find when travelling. The internet connection is really strong. The location, although it seems to be far from the main attactions is super. It has a carrefour in the same block, lots of restaurants open till late and a metro and RER station very close. And of course Nadji is super friendly and even takes the time to explain how to get around in the city. We will absolutely come back.
