Possibly the most bohemian place in Paris. This flat lets you experience the city like a local. The bathroom is tiny and the floors are uneven and the walk up to the flat is long and steep but I consider these all pluses as they are irreplaceable elements of authenticity. This is how young Parisians live, in a neighborhood full of energy. Sebastian is a thoughtful host who wants you to enjoy yourself, and you will.
If you're looking for bourgeois luxury, this is not the place for you. If you want to experience Paris like the people who make the city unforgettable (at a huge savings), grab the opportunity to stay here and savor every moment.
