We stayed for 4 days and had a great time. The apartment is close to a Metro Station, to grocery stores, bakeries, restaurants and bars.
There was a 4 page paper from our host that informed us about everything important concerning the flat and the neighborhood. The communication was also very good, the check in was easy.
The lock to the apartment was very tricky, but we where told so before, so we never gave up and always managed to get inside.
All in all it was a great stay in Paris and we we would recommend Alexandra's place to everyone who plans to visit.
