The apartment is spacious and modern. The beds are comfortable and the building is quiet (I slept very well!). The apartment is located in a quiet residential part of town. It's a ten minute walk to the Arc de Triumph and about the same walk (maybe slightly longer) to the Eiffel Tower. The apartment has a dishwasher and washing machine with separate dryer. There is also a drying rack and we noticed they provide baby things (we didn't need). It has wi-fi but it currently is very slow.
The local restaurant across the street (16th & Saint) was a nice place for dinner.
Because of the metro strikes, we had to Uber everywhere we couldn't walk (although we were able to take the train by the Arc to Disneyland one day). There's a closer metro to the apartment but it was closed the whole time we were there.
