This place in general is a good place, we had a smooth stay.
Good things:
The location of the appointment is very good. You can access M9 and M5 metro lines with 1 minute of walk. It is also very easy to walk to many nic places in 30 minutes.
Ben, the host is very responsive. The apartment itself is small but big enough for a couple to visit Paris.
Ben is as very cooperative to us, I made a mistake and booked the place one day less than what I expected but Ben allowed us to book another night in the last minute.
But:
I expected the place to be a little cleaner. The shower area is extremely small. I also expected to find at least two large towels, instead of two average size towels.
In general I think it's a place that worth it.
