We had an excellent stay at Marianne’s place! The location is only 10 minutes walking from Gare du Nord, which makes it easy for anyone taking the train. The apartment is very clean and cosy, perfect for 1-2 people. Note that there are 5 or 6 flights of stairs up to the apartment in case that would be an issue - but it also means there are beautiful views of Paris from the bedroom window. There are many excellent cafes and restaurants nearby, and it is a short walk to metro/bus stops, as well as to attractions such as Montmartre.
