Good location, close to Marais district and metro stations. On weekends there is a big market with fresh and tasty farmer food nearby.
But also in weekends there is open a night dance/music club "Clara" nearby and it makes the neighborhood not so nice and comfortable. Nothing criminal, though - just drunk quarrels in the morning.
The apartment has enough space for two people, the bathroom is small, as usual in Paris, simple set of kitchen facilities. But has all, that you need. The apartment is on the top floor and there is no elevator. Take it into consideration if you plan to have huge luggage. But you see sky and Paris roofs from your window)
