This flat is located between Iéna station of metro line number 9 and
Boissière station of metro line number 6. There is bus stop named Lübeck just in front of the flat where you can take bus number 82. It is really easy to access any visiting places within 30 minutes.
You may use Carrefour City which is French supermarket chain, located at Rue Saint-Didier. It's just 5 minute walk from the flat.
The flat is located 4th floor of the building counting from 0th floor. There is no elevator which you need to consider, but most of the building at paris city-center would be samely without elevator.
It was a really good chance to know how Parisien live, as it was a place where Estelle actually lived.
I've communicated with WhatsApp with the host Estelle and sorted out all the issues without any problems.
It was a really wonderful stay at Paris.
