Sofia is a great host kindly and warmly and helpful. The apartment is located near Bastille which have metro line 5 just front of the street (more metro lines and buses near Bastille)and bus No.69 just 3 mints walk (this bus passed most of landmark of Paris), i like to take this bus going to the center and you can see beautiful views on the way back near Seine river. This area is very safety and super convenience, a lots of restaurants super markets and public transportation around .
The room is very comfortable and clean, but if you are mind to share with Sofia do not disturb ,because its a share apartment she will sleep in the couch but of course separate spaces. 100% recommend.
