133 Suite Charlie is a good option for some travelers. The apartment is spacious and does have two separate showers and sinks for multiple guests. However, there is only the single toilet located in one of the shower rooms. There was no hangers or storage for clothes and things in the second bedroom which made it difficult to keep tidy. The beds in the apartment were uncomfortably hard, but I've been told that this is the way it is in Paris.
The apartment building has a gorgeous interior courtyard so when you come down the stairs you can situate yourself before being on the street or you can look for your keys in your bag without being on the main road. (This is good because the apartment is close to a section of the main avenue that isn't the safest street at night.)
Overall, the apartment worked for us for a few days. The air conditioning was helpful to keep the apartment comfortable, but didn't reach the back bedroom as it is too small a unit. The apartment was very clean and minimalist design.
