Overall: The place is definitely a crash pad for those only looking for a place to sleep in a great location in Paris.
Cons: I arrived the day after my reservation began, and Frederic was still late sending the entry code. I had to walk around on the street to find free WiFi to communicate with him. This was VERY stressful after 14 hours of travel. Entry instructions were very difficult to understand. It’s incredibly difficult to use the sink, as there is a shelf directly over it that blocks access. The shower is also very difficult to use, as others have mentioned. There are A LOT of house rules that Frederic sent to me multiple times. The walls are paper-thin.
Pros: It’s cheap and in a great location. The host is very hands-off during your stay, which I’m fine with.
