The location, apartment and host are all absolutely as good as it gets. Staying in the Marais means everything from the allure, Ile de Cite, St Germain and Bastille are within a short walkin distance. The apartment has windows on two busy streets in the 4th and watching the world go by is a separate joy. Paolo was helpful, informative and pleasant, and I would recommend any of his apartments without restating. So to speak.
