The apartment of Nicolas is very beautiful, tasteful furniture and well thought details. It's very clean and the view is stunning.
The communication with Nicolas was very easy, but I never met him in person.
The area is one of my favourite of the city, very young, multicultural, bohemian, close to the canal de saint martin/parc de la Villette/Buttes Chaumont.
Be aware that there is no elevator and the flat is on the 6th floor!
