I unfortunately never had the chance to meet Cello but she is so lovely and was available to answer any questions I had the entire time. This place is cuter than pictured. Its small but hey every apartment in Paris is small. No real issues, be cautioned that the images of the bed are of a single and double, not a daybed that folds out to a double. If you book as a single you get the single. Its wasnt really clear to me but really overall not a big deal. At the top of the street (literally 30 sec away) there is a Pâtisserie (open tues - sat only), grocery store and restaurants. The bus is at the door step of the apartment and metro is a short walk (6 mins). I like to walk and explore and walk home from notre dame (not a brisk walk) it took about 25mins. Maybe 20 mins to Luxembourg gardens. I travelled alone and never once felt unsafe.
