Location: 10-15 min walk to Eiffel Tower.
Bldg: Typical Parisian bldg which is the experience I was looking for. Bldg entry with security code. Spiral steep stairs to apt on the American 3rd level. There was no light on the stairs though, which was the only downside. I used my phone light to get up the stairs. Also if you have huge heavy bags, you might want to think again - but I think that applies to most buildings.
Apt: The apt itself was a cute and clean with a queen size bed, I think. Bed and sheets were very comfortable and clean. Heater/Cooler under the window, which was a peculiar location, as the curtains covered it. I had to tuck the curtains behind it so they would not block the heat. It would have been uncomfortable without the heater in December, so I was glad to book an apt with it. There was also a USB charger that worked out, since my international phone adapter blew. There is a mini-fridge that is convenient.
Bathroom: was clean with an upgraded shower and a large hot water heater which was really nice after a long day walking in Paris or on a cold morning. There was also an interesting electric rack along the wall to dry wet clothes.
Local restaurants: Indian, Pho, Grocery store just 1 min walk - which luckily were open on Christmas when almost everything else was closed.
Overall I am really glad I booked this apt and had a great stay! Kiki was prompt in responding via email and with instructions for getting into the apt. Was also amenable to let me check-in early.
