Spacious apartment, very comfortable for my husband and I.
Everything was thoughtfully provided - the kitchen had everything, the bedroom had spare bedsheets, and spare pillows, the bathroom had spare towels (and a towel rack to dry them if need be).
The coffee machine uses the large Nespresso capsules, so make sure to buy a sleeve on your way.
The place is very safe: there are secured gates to the building from the street, then a secured entry door to your section of the building, then the apartment door - with a key, and a deadbolt. Although the street was noisy, the place was quiet and peaceful the entire time we were there - no problems with sleeping and relaxing (which can be an issue in a large city like Paris).
Minor thing to be aware of (normal for large apartment buildings): water pressure depends on the overall usage, I.e., if your husband uses the bathroom while you are taking a shower, the shower will slow down to a scalding trickle.
Claudia was very responsive, and didn’t leave us waiting for anything. She was also extremely accommodating, when our flight got mixed up, and we had to arrive at different from the initially arranged time.
