My family enjoyed our time in this rental on the border of the 8th and 9th arr. It was very easy access to the metro, and has multiple supermarkets within a close radius. There is also lots of shopping nearby.
The apartment looked just like the pictures and was very comfortable for our group of 4. The beds were comfortable and had nice linens. Only one bathroom has a shower. The bathrooms were both larger than we expected, and the whole apartment has tons of windows and skylights offering great lighting. The rental also has air conditioning, which had a separate control for each room so everyone can control their own temps when needed.
The apartment is located in a building that is primarily businesses and is quiet. It's on the sixth floor and the lift/elevator goes to the fifth, so you will need to take your luggage up one flight of stairs. When going to bed, you can feel a gentle vibration of the metro even though you are many many floors above it. The building is secured by a keyfob for access and the apartment door has a sturdy lock for safety.
You can get to pretty much anywhere in Paris on the metro in 20 minutes. We enjoyed our stay and the convenience of all the amenities nearby. Great week in Paris!
