Loic is a great host. He greeted us at arrival and departure. The flat was just as advertised. It was more than enough space for our family of 4. The stairs (as clearly indicated in the ad) add a level of aerobic workout to the end of each trip! I always appreciate a good stair workout (but dragging more than a medium-sized suitcase up the stairs would be exciting!). We loved the store just downstairs and pretty much picked up meat, cheese, bread, and fruit on a daily basis at the end of each day for the next day's breakfast/lunch. Local bars and restaurants were good choices. We found that Chaufer Privet (French Uber) was often the best choice since we were 4 riders (train was about 6 euros and most rides about the City were between 5-10 euros). Their rates are typically much lower than Uber (especially in the summer when many of the Parisian users are away on holiday). I liked the 15th Arrondissement (it was quiet at night and I was comfortable letting my teens wander around alone). It is close enough to most of the places one would visit and the train lines (and ride share) meant that most things are no more than 20-30 mins away.
