I had a great stay at Julien's for just over two weeks. Coming to France during the covid-19 crisis, I worked from the flat - it is worth bearing in mind that there is no desk in the room for anyone in a similar situation.
The room itself is clean, roomy and the bed is very comfortable. Guests have a private shower and sink, sharing the toilet with Julien and his very sweet daughter.
The kitchen has fantastic facilities with everything you could need and more. Guests have a shelf in the fridge, access to the freezer and a shelf in the pantry. The balcony is fantastic! Beautiful plants and a very sheltered space to feel outside.
Julien himself is a warm and welcoming host, who always stops to say salut. On my first day, he offered me fresh fruit and veg, and advised me about the area. I felt he would be available if I had any questions. The flat is very bright and spacious, with lots of greenery and interesting bits n bobs.
The area itself is very lively and there are always people about. I felt safe walking from the metro stop (a 5 minute walk) back to the apartment, however, I may not have done this on my own beyond midnight. The centre of Paris can be very quickly reached by metro and the Gare du Nord is a stone's throw away. There are some fantastic places to eat nearby and a supermarket 5 metres from the front door. The building has a family feel with lots of children and is very secure (two locked doors at the front).
Overall, I wholeheartedly recommend Julien's wonderful apartment. Merci!
