The location is absolutely perfect: central, yet quiet. Plus access to every kind of shop and transport is convenient. And, Stephane could not have been nicer or more helpful.
This is a central Paris apartment, so expect the rooms to be small. But, they are well-outfitted. Only complaints: kitchen is minuscule and difficult to do anything in; downstairs bedroom has no natural light - not a surprise, given the description - but, it is very warm (even with the fan). And, the bathtub downstairs is very narrow.
We nonetheless had a wonderful stay and would very probably go back there.
