The good: The location is fantastic, the place is a good mix between modern and old furniture, the beds, sheets and linens are hotel quality.
The bad : no Wifi, the connection drops every minute, no 4G also and non cell network (Bouygues operator), and the host cannot fix the wifi, I had to go to a coffee shop to work. No Aircon also (I think it's fake as I cheked and there are no pipes linked to it). The 3 TVs are via wifi, so no Tv because no wifi. No vaccum, there are 2 in the apartment but one is broken the other one is missing a charger, we asked but never got one. There is an iron but no iron board, I had to threaten them to iron on the bed before they provided me with one. Microwave display is not working so you have to guess the settings. The place was quite clean except the toilets that had scale stains (we called private cleaners to re-clean the bathrooms), there are coffe pods on the picture but no coffee machine to use them (two other coffee maker were there but with a different system). And last, cupboards are full of junk, so you basically have to live out of your suitcase.
The unacceptable: invasion of drain flies every morning in the kitchen sink, disgusting.
Conclusion: Quite a nice place to stay if they fixed some issues, the agents are quite useless as they cannot contact the owners, lots of the items in the listing description seem to be fake (AC, ironing board...). But, if you need Wifi for your work, the place is to avoid, the host just cannot fix it, we stayed there 3 weeks and quit asking for wifi as they just cannot fix it (it is a shared connection between several apartments)..
