This place good for two couples and it is located in a nice area where you can easily access to public transport and there are plenty of nice restaurants and stores within 10 mins walk. We had a nice stay there.
However, there are a few things of this place that are giving us headaches. It is on the second floor of a building without an elevator, which means you have to carry your luggages up the stairs, the the main bedroom is on the upper floor of the duplex, so the couple living upstairs will have to lift up their luggages as well since the actual apt is slightly smaller than you see from the photos, theres not enough space for everyone to layout their luggages in the living area. What is more, the sink of the both bathrooms didnt work well so be prepared there will be flood after shower.
Overall it is good enough for our stay in Paris.
