Julien's place is a great place to be based for a short trips to Paris. Well located to the sites, metro and Gare de Nord. Lots of great local tips (including an interesting story about the building), and yes there are stairs but you're in Paris, a city full of old buildings so it's to be expected. The space is a cosy but again space is scarce in Paris and we were fine with two large suitcases, a small suitcase and a duffle bag in the room. Julien was easy to get in touch with, and promptly fixed an issue with the bathroom that we had.
