The most important thing about Arthur's apartment is that it is very, very hot in the summer. If you go to Paris in the summer, look for options with air conditioning or at least a fan.
In terms of location, it is more than 1km from any subway station.
As for the host, I did not know him personally. All communications went by airbnb. But let me warn you, do not expect too much courtesy from Arthur.
We were with a 1 year old baby and the heat was unbearable. I asked Arthur if he could not get two fans. The answer was cold and dry. "No. You already knew it was hot when you rented." I had to buy a fan, which cost only € 30.00.
As we were having a baby, I asked Arthur well before we arrived, if I could get a crib for the baby. The answer was dry. "No. If you want to buy one when you get there."
At the end, I asked if I could leave the apartment a little later. The answer was. - Leave at 10:00, because the maid will come to do a cleaning.
I mean, dear, Arthur, I suggest you be less machine and more human. With certainty you will have better qualifications in the future.
Best Regards,
