Good:
Location is great. It is near a metro station, and a short walk from the Bastille, Oberkampf and Marais neighborhoods. Lots of things to do in proximity to the place, and with the metro station, very easy to get around to other parts of Paris.
The place was clean and well appointed, and the building is secure. WiFi was very functional and had a good bandwidth. Chokri was generally responsive

Bad:

During this time, there is construction taking place just outside the unit. If you are there on vacation and want to sleep in, the noise from this construction will be a problem.

Bathroom sink had an odor which became more pronounced when using the tap. This was a major negative for our stay, and we managed the best we could. During the booking period and afterwards, we were not getting responses from Chokri, so we rated his response rate poorly. It was disconcerting not getting word back from the person whose place you are renting, and we were forced to consider if we needed to plan for alternate accommodations.
