We stayed in Marie-Hélène's studio for a week and enjoyed it very much. Marie-Hélène was a great hostess and helped us very much when it looked as we might need to go to Paris by car. Marie-Hélène found parking possibilities in different distances from the apartment and to different prices; fortunately we did not need them.
The studio is in fact situated in the middle of Paris. A lot of things to see are within walking distance, and anyway public transportation to all Paris sites is around the corner.
The studio is obviously a place where artistic work is being done and we found it very charming. Some of Marie-Hélène's artefacts are hanging on the walls and a big painting was standing on the floor, a nice one by the way. We were happy to get a bit of insight in her artistic work that way.
Do not expect new floorboards - the floor is in rough cement and paint-stained. But it was clean and we found it charming.
