Great apartment in the center of everything. Has everything you need for a stay in Paris.
There were 4 of us traveling together and the apartment was perfect for a short stay. The kitchen and bathrooms were fully stocked. The location is great, within walking distance of a lot of great sites, and a short walk to the metro (~2 minutes). Checkin instruction was super easy and we had the option to leave our baggage in one of their lockers had we arrived or departed late.
The apartment might be better for couples or friends of the same sex staying in the same room together since the ensuite bathrooms have no doors from the bedrooms.
We enjoyed our stay and will stay at one of their apartments next time in Paris.
