Sophie's place was awesome for a first stay in Paris. We had trouble reaching her before the stay to arrange check in but luckily we were able to get in touch with her after reaching out to AirBnB. Felipe, her neighbor, greeted us and checked us in. Really wonderful and hospitable! The balcony was amazing and it was a great amenity that many places in Paris did not have available. The apartment was the perfect size for two people.
Location wise, we walked to everything. We only took an uber to the airport (because the RER was on strike) and to the Eiffel Tower. We did not take the metro once but it is close to the RER stop by Luxembourg Gardens. The apartment was a 20-30 minute walk to most touristy places (Louvre, Marais, etc). The nice thing is that there's a pretty lively strip of bars and cafes/restaurants a 10 minute walk away from the apartment.
Apartment wise, bed was very comfortable. Bathroom and tub was clean. Kitchen was also useful.
I would stay at Sophie's again without hesitation!
