I enjoyed Christine’s studio for one week (in August). It has just the right stuff for one person. A modern apartment in an old building in an even older section of town, it’s very convenient to the center of Paris. There are three metro lines within 10 min walk. The room got warm during the day, but Paris cooled off at night, so the open windows and small fan were sufficient for comfortable sleeping. [Hopefully the construction across the street ends soon; the 7:30 am jack hammers woke me up.]
