We stayed in May for 5 nights and had a great time. The place was perfect for my daughter and I. The bed was really comfortable and the water pressure in the shower was great. The flat did have a bit of a musty smell when we first arrived, but we just cracked the window when we left everyday and it was gone.
The area was perfect and walkable to everything. There is a bakery and grocery store close by, which was really convenient. I would definitely stay again if I travel to Paris in the future.
