This place is awesome! It's WAY more spacious than most other places in Paris, AND it has air conditioning. I absolutely loved having a large kitchen to work in. The large oven/stove, large refrigerator, and microwave made a huge difference.
The walk to the metro is not far (about 5-7 minute walk) and it has almost every convenience you would need. Just on the way to/from the metro there are nice grocery stores, pharmacies (easy access to COVID testing), fast food places, pastry shops, restaurants, ATM's, salons, clothing shops, miscellaneous stores, etc., etc. Plus it's only two blocks away from an entrance to the famous Pere Lachaise Cemetery!
It might seem a bit far from the main attractions of Paris but it isn't that bad. It's 100% doable. We brought our 9 month old baby and went out to see the sites every day for two weeks and it was not a problem at all.
Our host Bilel was really great to work with. He is very responsive, communicative, and happy to help out. He made sure that the home was totally ready for our stay. We were only there for two weeks but he left enough supplies to last two months if needed.
The apartment itself is located in a very safe, family friendly, area. There are two doors that need a security key that you will pass through just to get into the building. After the first security door there is a large courtyard with lots of plants and often kids playing. The balcony is large and overlooks a separate smaller green space. It was very pleasant to spend time there in the evenings. You can even see the spotlights from the Eiffel Tower shine on the clouds at night from there.
