The place is very centrally located in a safe neighbourhood, about a 5 min walk to the nearest metro station, Porte de Choisy, and about a 20 minutes train ride to the Louvre on a direct line from there. Lyon and his co-host, Thierry, were extremely hospitable, kind and respectful. The room and bed were also very comfortable, and I enjoyed my stay there. They were also very flexible with the check-in and check-out time, and were very responsive and communicative.
The hosts also added little touches like a fortune cookie on the bedside table, and were very welcoming and helpful in all ways.
The neighbourhood is very safe even at night, and there were many restaurants, shops and amenities nearby.
Merci for the lovely stay in Paris, Lyon & Thierry! :)
