We enjoyed our stay in this apartment. The location was fantastic, and very walkable to everything we wanted to see, do and eat in our 2 weeks in Paris. We really enjoyed the space and openness of the apartment (which for context is bigger than our apartment in Amsterdam). And we enjoyed coming back to the apartment each night after exploring Paris.
Somethings to consider, and potentially message the Host about before you book:
The kettle - unless this has been replaced, it's best to keep unplugged when not in use. The one in apartment when we stayed would keep trying to boil even when not switched on.
Bathroom - when we stayed, there was a fairly strong odor in the bathroom, most likely from the shower drain. Again this might not be an issue anymore. The towel drying rack can be a little tricky to turn on since the handle/dial is broken, but it does work well.
Noise - depending on how light of a sleeper you are, there's about a 4 second buzzing sound that happens intermittently which can heard from the bedroom (my guess is the air-conditioning unit or the the fusebox, both are next to th bedroom door). You get used to it after a while, but if you're a light sleeper and only staying a night or two then I suggest messaging the host to see if this is still happening.
