I had a lovely stay at Isabelle's studio flat in the China town district of South Paris. The studio was clean and tidy, the bed was comfortable (if a little squeeky) but very comfortable, the provided sheets and towels were also fresh and clean.
The studio is in a private courtyard beyond a key fob activated gate off the street so nice and safe, the studio also has electric shutters to cover the windows and doors as required.
Isabelle was also really accommodating with check in and out times and also available on email, I never needed to phone.
I wouldn't hesitate to stay again, highly recommended.
