In agreement with all the other reviews, Jerome is a gracious host. He checked in with us several times to make sure we made it to the apartment and were able to check in without issue, and that we were comfortable.
Access was a little challenging as the keys to the entry and apartment are more sensitive than I am accustomed to--we struggled with these briefly before finding success.
The apartment is tidy, but not spotless. I would describe it as Ikea grunge. It is artsy but lived in. The host obviously lives in the space and I appreciate that this is a true owner hosted AirBnb. It could use a thorough scrub though, and the toilet smells used. Not unlike crashing at your cousin's apartment while he is out of town.
As far as well-appointed, the basics are there to survive and make due. After searching for a decent knife I found myself slicing bread and cutting cheese and fruit with Ikea steak knives. I didn't attempt using the tiny dishwasher (very cute!) but washed my dishes by hand instead.
Ambient noise doesn't bother me but for those who are sensitive, you do hear street noise and feel the rumble of the Metro like a distant thunder into the early hours. The cross breeze is very efficient at cooling the space quickly.
For the price, this apartment is a great value. It is perfect for young travelers who want to get the most out of Paris on a tight budget.
