The private rooms are amazing, very much like a hotel without the price tag. I was surprised at how large the room was especially compared to hotels I’d stayed in across Paris.
My only issue is that the walls are very thin. After 12am it was fine but before that I struggled to sleep because of people coming in and out. Even someone having a shower in the room above me and their phone vibrating was quite audible in the room.
Location was amazing, close to two stations with many different lines. Had no issues arrive late and leaving early.
