We stayed here as a family with 2 seniors, 6 adults, and 2 small children (age 18 months and 4 years) and had plenty of space for everyone. If you're visiting during the warm months I highly recommend renting the rooftop terrace - we loved sitting there in the evening with a glass of wine, charcuterie, and the priceless view of the Eiffel tower. The area is quiet with plenty of cafes and markets nearby. Because we had two older adults and children in strollers we ended up using Uber to get around rather than public transport, but you could easily use the Metro if you have a more mobile group. Tip: Bring your own washcloths as most accommodations in France don't provide them.
