Arthur's apartment is beautiful, with a terasse overlooking a verdant park, good light, and furnished like a proper Parisian flat. Clean and attractive interior decor. This is not a dedicated rental unit, but a real lived-in Parisian apartment, which makes it comfortable and a great place to retreat between long outings. Two of us shared the spacious bedroom, and a third used the sofa bed, and all slept comfortably. The neighborhood is fantastic: very vibrant and rather bobo, full of interesting shops, bars, and restaurants, but not touristy. We did quite a bit of Xmas shopping during out stay and some of the best was here.
The one issue we encountered was minor. Arthur explained that he had not been using the radiators for heat, but instead some electric space heaters. We tried to follow his instructions to turn on the radiators but failed, but indeed the space heaters sufficed.
Overall this was a great and authentic experience.
