The apartment is in an excellent location, with 3 metro stations within walking distance to many attractions and 10-30 minutes by train to others. One of the stations is just across the street.
Valerie was very good with communication and gave some helpful tips.
As some others have pointed out the apartment itself is presented well with all basic amenities sufficient for a brief stay in Paris. I was prepared to be in a small space, especially the toilet, and it was indeed difficult to use it but I would still recommend the place if you can manage a few uncomfortable minutes in the toilet ;)
