We really enjoyed staying in this flat. It was clean and comfortable. As everyone and the pictures note, it is small but it was perfect for my daughter and I. The flat has a roll out bed under the bed - both beds were extremely comfortable. The bathroom is a bit tight and the floor got wet every time we showered but this did not pose an issue for us. The train is a 5 minute walk and very close to tourist attractions. There are also a few markets to shop a few steps away.
I would highly recommend this flat to anyone staying in Paris looking for a homey place during their stay. It was very cosy, the neighbors were friendly - much more so than most neighbors of Airbnb guests - and there are plenty of good eats nearby, especially the bakery around the corner.
