This apartment has such a great location - walking distance to Gare du Nord and Gare d'l'Est, close to Canal St Martin and Republique, and cool street/church views. The old flights of stairs in the apartment building also have a lot of character. It's perfect if you want to feel like you are a real Parisian!
The apartment was comfy and clean, however be aware that it is really a studio apartment (the bed is behind a curtain, and when we were there, the single easy chair in the photos was missing so the only seat to relax on was the sofa. The kitchen area is fine for small, simple meals, but not quite a 'full' kitchen ( but who is doing much cooking in Paris?!).
Just be aware also that like many properties in Paris, this is also someone's home... but in a way that adds to the whole experience of your stay.
We enjoyed our stay and felt that this was great value for a super location.
