We (two people) stayed in the apartment at 52 Boulevard Richard Lenoir for one week and enjoyed our stay.

PROS:
- Location is awesome, with subway station (Richard Lenoir) nearby and the Bastille square only 10 minutes away by walking. Subway line #1 which stops at Bastille is super convenient to go across Paris.
- Neighborhood is safe and convenient.
- Apartment is very clean, well organized, and well equipped (microwave, burners, oven, dishwasher, washing machine, bath tub, kitchen equipment, dining table and chairs, Wifi, TV, cleaning products,...).
- The bed's mattress is very good and the beddings of good quality.
- Balcony is convenient.
- Building is well secured.
- Casino supermarket is nearby, also opened on Sunday until 1pm.
- The person handing off (Chokri, at that time) the key was very nice, on time, and efficient.

CONS:
- The apartment is definitely on the small size and could be a challenge for more than 2 adults, but again, it's well laid out.
- No additional bed available, but again, it's best geared for 2 adults.
- There isn't much natural light, even on the balcony, since the building is actually in another building's courtyard.

Overall, I definitely recommend this apartment, especially for a price up to the $70s/night.
