Excellent place! The apartment is very central right in "la bastille" square and walking distance (5 min walk) from the heart of the touristic and charming area of "Le Marais", a pittoresque Parisian district. The area is safe, and has lots of very cool bars, restaurants, cafes, bakeries. There is also a grocery store right next to the entrance which is very convenient.
The apartment is small (the only downside) but perfect for a loving couple. It is renovated and very clean. No noise from the street (very well isolated from sounds), and the place has lots of amenities. Wifi, TV, fridge, mini kitchen, everything worked well. The sofa/bed is super comfortable and the sheets/pillows/towels were all clean.
I would definitely stay there again. The price is worth given how central the apartment is.
