Very original flat, it's not the usuale one. You feel that's the home of an Artist. Jean has been very kind and helpful. Even if he wasn't in Paris on this period, he gave us all instruction very well. We had no problem to go in and go out. He has been very understanding and let us in the flat until late afternoon on the date of our departure. Not real problems, wi-fi working well except one day but Jean was able to help us to reconnect. Air conditioning is working automatically so you cannot control it but the air rechangement was good. We didn't need cold air. Flat is situated on internal courtyard, so if the other guest are good you have no problem of street noise.
The only real problem could be the narrow and uncomfortable spiral stairs to go in. If you have some moving problem or heavy luggage you can have big problem. Also there is a spiral staircase inside the flat can give problem too.
Therefore, if you are looking for an unconventional and pretty artist house, you are on the right place. Thank you Jean.
