The check in was very easy thanks to the app Christopher uses. The neighborhood is very interesting and lively. You can reach all the main tourist attractions by the metro lines near the apartment. But beware that the apartment is very small! It is not easy to understand it from the photos.
If you want clean bed sheets and a clean toilet only, it is an OK place. But we think it is not enough for a nice stay. There were lots of cleaning utensils on the bathroom floor but the whole place and the wardrobe were full of dust. The bed makes noises whenever you move and you hear everything your neighbors do. Even the fridge makes a funny noise. We had to turn it off.
The place is below the ground floor. We had to keep the only window we had closed the whole time. And it gets cold! The heating is not good enough.
It's not easy to find an affordable and nice place in Paris anyway. But we still expected this place to be better than it actually is.
