The studio was clean and well situated. The photos are professionally taken. The person checking us in was late. We locked ourselves out and we were charged 100 euros by the agency to get back in - just be aware. That was our fault to be fair and the agency were very responsive. The kitchen is not well stocked in as far as basic ingredients but we never used it anyway.
The major issue with this accomodation is that the surrounding neighbours are extremely hostile to temporary residents but this might be a problem across Paris...
