A great location in a busy and exciting part of Paris, with the opera, shops, restaurants and train stations nearby. You could walk the streets at night and feel at ease due to the many people around, and it wasn’t noisy in the room which was good.
The building itself is very narrow and tight (stairway and corridor), no numbers on levels or apartment doors is a bit strange. Going up and down the five flights of stairs with luggage is difficult, would not recommend for unfit or immobile people. The apartment is small, it has been furnished nicely but for two people it is a tight squeeze, especially in the bathroom. Mattress is lower than usual.
On the plus side, a small kitchenette and TV with Netflix.
