The stay at Adélaïde and Philippe’s place was great! Very hospitable and charming people, and can answer all your questions about getting around the city. Another important point - Location, location, location! Their place is located 2 minutes from the subway (metro), about 25-30 minutes from the Arc de Triomphe and 40-45 mins from the Eiffel Tower (both of these by feet, which allows you to see Paris beyond simply the touristic sites). The subway to get downtown is about 15-20 minutes also, which is great! Would definitely recommend.
