On booking and arrival everything was very efficient and helpful. I can see why he is a superhost. The apartment is on the second floor with a lift. As others have said it is very spacious with 2 bedrooms each really are both en suite and then there is a third toilet if the ensuites weren't enough! The shower cubicles are small so you have to 'fight' with the shower curtains and be careful not to allow the water from the shower to flood the rest of the bathroom. The shower curtains were very clean though. There is a washing machine which was helpful as we stayed a week. There is also a drying rack and pegs supplied.
One bedroom is at the front of the apartment along with the two main living areas. Big windows open on to narrow balcony's that have some plants on to make it feel nice. For people not familiar with Paris the road the apartment is on is a very busy road so there is traffic noise night and day. We had to keep the windows closed at night while sleeping to keep the noise to a minimum which did mean it was a bit uncomfortable with the heat. A fan or two might be helpful just to circulate some air.
There is a good amount of storage/hanging space allocated for guests and as the rooms are so large it was easy to store our suitcases away.
In the kitchen is a fridge and freezer as well as a big cooker and poweful microwave etc. We only used the oven to warm croissants but it worked well. There is plenty of cups, glasses, plates etc.
There are a number of supermarkets close by but remember most are closed on Sundays. However there is always the corner shop for essentials. A few teabags, coffee, toiletries, cheese, milk and water were provided for us on arrival which was a lovely touch so thank you.
There were also numerous bits of tourist information left out including a metro map and street atlas.
The wooden floors are lovely and do creak a lot. I suggest taking slippers or socks to wear in the apartment to protect your feet. There was hardly any noise from the apartment above so they seem well insulated. The communal areas are well kept and clean. Security seemed good with locks etc.
The area is busy and bustling which added to a real Paris experience rather than a non personal hotel room.
