The apartment is very charming in an old building . It id very clean and very good equipped.
Although it is on a main street in a 2 minutes walk from Eiffel tower it is calm in a safe neighborhood.
The metro stations are in some distance but the walk to them is beautiful :) There are nice restaurants, bakery, pharmacist and shop next to the entrance of the building.
I sincerely recommend Davis as a host and his apartment.
