We’ve stayed in the flat for 6 nights and for our family of 3, it was perfect. It’s quite cozy but not tiny as some of other flats in Paris we’ve seen. Everything is brand new and spotless. The bathrooms (there are two, which is lovely for the morning rush hour) are better than on the pics: new, clean, proper water pressure, just perfect.
There isn’t much of a “hood” around the Arch, but there are several bakeries within a 5 min walk and 3 different metro stations, which made all of Paris very accessible.
Having a concierge also makes life that much easier when it comes to storing luggage, borrowing umbrellas etc.
We really enjoyed the stay and can recommend the flat.
