We enjoyed our stay in your appartement.
All was good, the only thing for my parents in law was that the appartement was at the 6th floor. It was a bit high with many stairs ;-) For older people or kids and when it's very warm it can be tough.
And the neighborhood was a bit tense on the street in front of the appartement..with a lot of noise, small incidents with police and people from the neighborhood etc..we woke up sometimes because of those issues.
It might, because it was extremely warm (34 degrees) we had to open as much windows in the night to cool a bit, we heard so much street noise. When the windows would have been closed it would have been way less probably
