The apartment is in a great location. While on a busy corner, surounded with bunch of cafes, I never had any issues with noise after like 11-12pm. It is relatively big, for Paris standards.
Pierre was quick to respond and accommodate my requests. Check-in was relatively easy though you have to coordinate in advance. The only thing that would make this truly a five star property will be adding more small stuff, like an extra trash bag, a new kitchen sponge (and not leaving the one that clearly has 100k millage), regular toiletries etc.
Overall, I'd stay again in this apartment.
