This apartment is very central. My 65+ year old mother always wanted to see Paris and from l'Opera area we could easily catch metros or walk to the major tourist points in the city. We picked this place because it has a lift and AC, both of which made her more comfortable.
Overall, we understand space is costly in the big city. This is a small, simple, apartment in a big city. It is nothing luxurious but it is efficient and (again) very well located.
