This is a great flat in a quiet secured courtyard area, so it is very safe and private. It's on the first floor on the building at the end of the courtyard. The flat itself is very comfortable and was great for our 5 day visit to Paris!
There are lots of great restaurants relaxed restaurants that we tried in the area around the flat.
The flat is also near the Metro stations Chateau d'Eau, Saint Denis, Jacques Bonsergent and the large hub of Gare de l'Est. All sorts of Metro lines depending on what you need! There are also great little shops around there for your grocery needs such as Franprix.
