I can't say enough about the fantastic location!! In the middle of the Marais, with its lovely streets, little shops and lots of great & cozy restaurants, but still quiet at night. You can do lots of things by foot, the Seine is just a short walk away. The same applies for the metro station, no problem to get there from Gare du Nord. Also, the area feels very safe.
Aurélia was great, even though we didn't meet her, she was quick and very friendly to answer all questions. The place itself is a cute apartment, Wlan worked great, and we slept very well in the bed with the huge blanket.
