Location is fantastic; couldn’t be better. Very clean and slept 3 comfortably with all the necessary items for cooking. It’s small, but what do you expect for a prime location in Paris.
The only issue was lack of Wifi which was easily remedied with a 30 Euro SIM card and making my phone a hotspot for everyone else.
It was myself and my 12-year old twins and they loved it.
The stairs and lack of elevator wasn’t a big deal. We left the heavy luggage under in the stairwell on the first floor and took lightweight clothes for 3 days to the apartment.
I also recommend using the Velib bike rental for 5 euro a day to get around Paris.
We took a taxi to the Apartment from CDG and an Uber from the Apartment to CDG because it was an early flight.
