Location location location. Prime real estate. Live (almost) like a local in a fabulous location with Luxembourg Palace in your backyard. The Seine and Notre Dame is less than 15 min away by foot, the Pantheon 10. The Catacombs are in the other directions. Subway station and bus stop are also easy to access from the apartment so the rest of Paris is easy to get to as well. Just locally, the area is great. I was very pleased with the location.
The apartment itself is an efficient two room apartment with all modern amenities including washer/dryer, wifi, and basic kitchen/bath (2 toilets!) and overall designed neatly so there feels like a lot of space, but 2-3 would probably fit comfortably in there max. I thought I had an issue with the stove because one of the pots doesnt work, but that was resolved pretty easily as Alain responded quickly.
Overall, it could use a deep clean, but if you're out and about it doesnt matter because it's a surprisingly lovely apartment and a great value for the spot. 10/10
