The property is not maintained, missing bulbs, non-working TV, in-operational bed room heater, broken , dirty and overly used cutlury squeaking floor even if you walk slowly, very small bathroom.
Also host stays out of France, several efforts to contact over phone failed.
Nearest metro is 11 minutes walk. Flat photos are misleading, host has not mentioned the apartment area but it seems carpet area is about 30sqM.
The property is at 1st floor so if you are planning to come with baggage or person with disability then it is not a place for you.
Also ask host to renew the main door lock as it is not working properly and never could opened in 1st attempt and every failed attempt increases your heartbeat with just thought of spending your night on street..
