Very comfortable room (with an exceptionally comfy bed). Nice bathroom with excellent, spacious shower. In general, despite being small the room is very well appointed.
The location is without equal, with loads of superb eateries and even a good gym just a few minutes away. There are also a super market and launderette literally thirty seconds from the front door of the building, while the local metro stop is at the end of the road: I could get from the apartment to inside the Louvre itself in about twenty minutes.
Extremely pleasant, helpful, welcoming, easily contactable hosts - I felt *completely* at ease throughout.
The stay was not entirely without hitch. The wifi (which for the record is the fastest I have ever had: my Ookla speedtest app clocked download speeds of 400Mbps
