Jerome and Sara are great hosts and very communicative. The apartment is beautiful and clean. But it is not meant to live during hot days.
We were there during a hot week, in which the temperature was over 30° for several days. The apartment is not comfortable to live, even with 3 portable air conditioning. The living room is like a sauna room. Also the air conditioning is very loud. The windows have to be open due to the duct of the portable air conditioning, which makes the outside noise of the street and trains more obvious. My daughter woke up at ~4 am for several days due to the temperature and noise.
