We did not meet Lily during our stay but communicated via What's App. The neighborhood is nice, very close to the Bir-Hakeim and Champ de Mars stops. The apartment is also very close (walking distance) to the Eiffel Tower. That was the biggest plus of her place. Safety was good as the entry door to the building required the green plastic key to get in.
The room was as the pictures displayed on the site but very comparable to a hostel. The apartment also served to store other items behind the couch.
The WiFi was not working when we arrived but Lily's brother came that afternoon to have it fixed. Once fixed, it was not that stellar. Only 2 devices could use the WiFi at a time and we had to repeatedly enter the username and password which was annoying.
Overall we were looking forward to a cute Parisian studio but this was more like a hostel.
