Fantastic host and place! Ticked all the boxes for our wonderful time at Paris - location (very close to metro station, restaurants/ cafes downstairs, essentials/ supermarket easily accessible downstairs, nice yet small balcony to relax at the end of the day), safety (seemed like a very safe neighborhood) and local culture experience/ tips (Mathilde was really spot on with communication via whatsapp or call and is a wonderful & personable host and the wifi is good in the apartment.
Please do note that this worked really well for 2 active people and the following points should be considered:
You are sharing a 2 bedroom apartment with a common bathroom with the host. There is a significant 5 floor climb which is especially tough/ cramped to lug big suitcases. On our return for a flight at noon, metro involves changing of lines with your luggage, taxis downstairs were not easy to find and Uber surge prices were (100 euro +) from 8am till later which takes about an hour to get to if it's CDG airport. It was very hot in Paris (30C+) and the apartment does not have air conditioning (small table fan) which could be tough at night. We knew all of this going in and have zero regrets.
