The space is ideally located close to many metro stops and the Champs-Elysées. It is incredibly loud with the windows open or closed. There is a bar next door which is open most of the night and the patrons were outside every night of our week long stay being quite noisy. There were also cars honking throughout the night as they drove past.
The room itself is very small but not a problem for short stays. With two people it is quite cramped. We live in a very small apartment but even so this was too tiny for us. The toilet is quite far away down a dark hallway, it is not right outside the room. It is also shared with the other rooms on the floor.
Be careful when using the water as the water and taps get extremely hot very quickly and I burned myself a couple of times on the sink and shower.
We never met Claire but she let us know how to get the keys from the building manager and where to leave them when we left.
The stairs are mentioned in the listing so it is no surprise but there are a lot of them (18 or 19) per floor. The stone pavers on the landings are a bit loose in spots so be careful as you walk as you could slip.
The wifi worked perfectly the entire time.
Overall this felt more like staying in a private room in a hostel (with shared toilet) than most of the other places I’ve stayed that are more like guest rooms in someone’s home.
