I thoroughly enjoyed staying at JD's flat, which is a great space. I spent 6 weeks there and would totally recommend it for both short and long stays. It is located on a side street in the lively 11eme, with lots of restaurants around and just a few steps from metro Charonne that conveniently connects with the rest of Paris, while Bastille and Le Marais are just 10 min on the bike. JD and Laetitia were very helpful and friendly. If I needed anything they were happy to help and very responsive.
