From the first message till the last goodbye Julien acted not like a host, but like a caring and considerate friend. He patiently answered all our question and was very understanding about changing dates and arrival time. There are people one trusts and likes right from the start, and Julien is one of them.
As for the apartment, it was perfectly clean, full of light, much bigger than on the pictures, very cosy and practical. It really feels like home. It is in a nice safe area, very close to metro and bus stations, supermarkets, bakeries etc. One can reach central areas of Paris easy and quick.
All in all, I can only recommend Julien's place very sincerely to all serious travelers. There are five flights of stairs, though, but this apartment is worth every step.
Thank you for everything, Julien, and I can assure you that we will be back :)
