In summary, when we return to Paris we will definitely stay at Roger's place again assuming that you dont book first. In the past 10 years I have spent around 3 months in many different arrondissments of Paris. The area where Roger's place is located, Bercy, is ideal if you want easy access to the central tourist attractions but prefer quiet evenings. Bercy is just barely on the modern side of the where 'old Paris' meets 'modern Paris' in terms of architecture and development. It is a mix of old style and 21st century building. You are still close to bakeries, coffee shops and restaurants but you can also enjoy the amenities that modern development afforts, like 3 layers of security that you must pass though to get to Roger's place, as well as, a parking garage if needed. Additionally the metro stop, 300 feet from Roger's place, is one of the more modern so it is equipped with escalators and an elevator.
Our goal was to have a relaxed vacation so we spent about 6 hours per day in 'old Paris' and the rest of the day at the appartment and restaurants. Our party consisted of two adults, our two sons 21 and 18, and our daughter 16. Our daughter slept on the sofa couch, which really could have slept a 6th person, and rested well. A TV was not critical but Wifi was, so we were relieved to find that the Wifi was fiber and our multiple connections didn't cause a problem. We didn't think that we would use the kitchen much but by the second morning we were gald to have a fully-equipped kitchen with a dishwasher. By eating breakfast in the kitchen each morning we got a relaxed start to our day. The washing machine allowed us to pack for 5 days but stay for 9. The terrasse was a bonus in the evenings as I enjoy spending as much time outside as possible.
This was our first Airbnb stay and we are spoiled. Roger and his wife were a pleasure to meet. Roger was extremely helpful with a specific request that we had. His communication was timely, accurate and attentive to details. My only caution is that - travelers with small curious children might spend more time than they care to keeping the children out of Roger's books and plants. Autrement bienvenu à Paris et la vie Parisienne.
