Value decent. The location is near great restaurants, walking distance from Seine, very close to large park great (good for runners). There is a train from the CDG airport that stops just blocks away! (But doesn't seem to run on Sundays.)
The apartment is grungy, but Parisian apartments are always grungy from an American perspective. The space is adequate, the bed is comfortable, and there is plenty of hot water! (Tiny shower though--fine for me, awkward for my husband.) Host is fast communicator, too.
The cleaning person does a good job with what she has, but I wish she were given greener products b/c the place had a very artificial, kind of gross smell--like air freshener in a room where someone was smoking.
Two big complaints:
1) no way to first get into the apt unless you wait for the host.
2) super under-appointed! No bedside lamps, no night tables, not even any trash cans--host said to just put trash in a bag on the floor. Makes the place less comfortable and somewhat sad.
