I stayed at Gilian's place in June 2021 with 5 friends. We all loved the apartment and were happy with the choice. The apartment comfortably fit 6 adults. It was bright, clean and comfortable. 4 of the 5 bedrooms have excellent air conditioning which was a plus for us traveling in the summer. A good air conditioning can be tough to find in Europe.
The location is fantastic. There are a lot of shops and restaurants right outside the door. A major metro stop is a couple minute walk away. Even though it's located on a busy street, the apartment is quiet and we did not hear much street noise.
Gilian was very helpful and responsive and was an excellent host.
I highly recommend the apartment especially if you are traveling in a big group. I would stay here again if I visit Paris in the future.
