I was in Paris from 29/12/2016 to 01/01/2017. The flat is perfect for a short stay!
The position is strategic, especially for those who arrive in Paris from Beauveais (750m from port Maillot).
Moreover, the arc du trionphe and the metro station Charles De Gaulle are very closed (650m) and from there you can easily and rapidly reach the heart of the city.
The host allows flexible check in if the apartment is available. Unfortunately, Rolando was not in Paris when I arrived so I was received by another person.
The apartment is really small but it is very well equipped! After few hours we got familiar with the restricted space and we found a place for all our stuff. It is located at the 6th floor but there is a lift till the 5th floor and then few steps.
The only negative point is that the flat was not as clean as expected. Since Rolando was abroad, he did not manage directly the preparation of the apartment for our arrival and he apologied for that.
Anyway, I have to report my experience and this is the reason of my negative impression on cleanliness.
