This little apartment had everything that I needed. The location was perfect for me since I arrived on Gare de L'Est and left via Gare du Nord. The building was quiet, and I slept well. I can definitely recommend this apartment for one or 2 people.
However, I think that it should be noted that there is no elevator.
The stairs are very difficult to deal with when transporting a heavy suitcase. I have to add that I am female, small and not young any more.
Nevertheless, I think that this is a great place to rent.
