We were a group of 7 and the property fit us well for sleeping. The beds are all comfortable and the ensuite bath in the master was convenient. Everything was clean and well decorated.
Things to know:
--you must download an app in order to obtain the codes for all 3 doors to get into the unit. Be sure to do this prior to arrival so you're not standing on the street figuring it out!
--there are stairs leading up to the apartment however the only rooms on that entry level floor are one bedroom and the small living room. The rest of the rooms are back downstairs within the apartment
--we were hoping for an area that we could all hang out in the evenings however the only space that was large enough to seat all of us was the kitchen table which isn't great for relaxing or watching a movie together and it is completely separate from the living area. The only lounge space is upstairs, off the master bedroom, and has enough seating for 3-4 people comfortably.
--location is convenient to the metro (about 2 blocks to the Gare de Nord station) and restaurants, however not in walking distance to any attractions. Every attraction (Eiffel Tower, Louvre, Catacombs, etc) are all at least a 20 min train ride.
All in all, the place was fine for what we needed.
