My stay at Lise's place was absolutely fantastic. Her apartment is a lovely glimpse into Parisian living. Lise had left notes and signs around the flat so that there was no confusion about what I was welcome to use, which rooms were available to me, etc. The room's balcony opens onto a busy street, so bring your earplugs or plan to sleep with the balcony doors closed. However, the activity meant I felt safe walking home alone even at night. The apartment is in a residential area, 3 minutes from a square with a metro station and some restaurants. It doesn't take long at all to get around on bus or metro, and it's well worth the small amount of extra travel time to get out of the busy touristic center of the city. Lise and I didn't get to have long conversations in person, but her English is very good and she was highly available to me via messaging for any questions. All in all this airbnb is perfect for a person traveling alone whether they've been to Paris before or not!
