This apartment is perfect for a small group, family with kids, or a couple. The location is ideal for sightseeing or living a local Parisian life, which we did both of. So many restaurants that are not tourist traps, as well as shopping and two metro stations within a 5 minute walk of the front door. We enjoyed staying in this apartment. It was stocked with the basics and clean. Enough blankets and pillows for all beds, and the heat never faulted when it got cold at night. We were comfortable.
One thing I would note - while this apartment does face the back road and not the main, as well as the courtyard, it is not completely without noise. From Thursday - Saturday night from 9pm - 1am/2am there is noise outside of the two bedroom windows from a bar one floor below. It does get quite loud as patrons are outside smoking and drinking and are right outside the windows essentially. You need earplugs or a sound machine (which we had and it worked okay).
We will stay again!
