My mother and I had a nice stay at Laurence's place. It's a clean and tidy space. The "cul de sac" that it's on is a nice area. The train walk is 5-6 mins away and as I remember about 15 mins to the popular center, Les Halles. The apartment is up a flight of steps at the door - nothing grave and then one flight up.
Fatma and her husband received us. They were very nice and helped us with our bags. She served us this delicious tea that was perhaps mint, and jasmine.
Thank you Fatma and family and Laurence.
(One general note about Paris overall, try to prevent having multiple bags if possible b/c of the many steps involved in taking the metro. )
