Opera is such a perfect place to stay in Paris because it's very walkable between everything. This airbnb is on the 4th floor and yes, there is an elevator :) The windows look out into the courtyard, which is cute and serene. The apartment is on a street with a few charming restaurants and cafes. While there is only 1 toilet, it was nice to have 2 showers in the hot Parisian summer. The bathrooms are really nicely remodeled with floor to ceiling tiling.
Only thing to keep in mind – you are given 1 key to the front gate. But you do also have keys for the 2 bedrooms, so it's an option to lock the bedrooms and leave the gate key in the lockbox downstairs if you're planning to return to the apartment at different times from your traveling partners.
