I stayed at Claire's studio for two nights. It was really quite lovely. Claire greeted me after I took the lift to the 5th floor of the building. She is really a wonderful host. The studio is very nice, accommodating and clean. All the things you would want. Nice to have a fridge and small kitchen too.
The apartment is in a great area for anyone visiting Paris. Close to metro and easily walkable to many parts of the city. The building is secure so you feel very safe. I would def stay here again!
