The greatest value for this place is its location. Very central and very close to the metro station, specifically, RER line B, which goes straight to CDG airport. It is literally ~50 meters from the metro exit to the entrance of the building.
The appartment is on the 5-th floor with no elevator and the stairway is a narrow spiral in an old building. Carring large luggages can be a challenge. The appartments is basic, but necessary things are there. The show cabin is tiny, large person may not fit.
At night it can be noisy, since the building is on a narrow but a busy street with multiple eateries at the ground level.
