My husband and I stayed here on an extended weekend trip. The pictures were accurate and the place was very nice, clean, and well organized. The apartment is easily located near the metro. If you don't mind a lot of walking, you can definitely get to some of the inner parts of the city, but it will take some time. We walked awhile and then rented bikes to get to the Eiffel tower. We found that by metro though it only takes about a half hour of less to get most places.
This is a lively neighborhood, lots of city noises, but not overly touristy. From our observations there was a wide mix of young adults and families. There are dozens of restaurants in every direction. There is also a nice street market on Saturday.
Tristan was very responsive to questions. This is a lived in apartment and not one of those Airbnb listings that is clearly only used as an airbnb. It is definitely a nice, clean, urban apartment (personal enough not to feel stale but not at all cluttered with personal items). It was a great value for us since we were looking for something more affordable than anything close to super touristy spots but still in the city limits and close enough that you can get downtown fairly quickly.
