We spent in Paris 7 wonderful days.
Sam kindly hosted us in his apartment. It is on the last floor with no elevator but cool vintage stairs. It was ok for us, but for some people it could be a problem.
It has music atmosphere: guitars and music collections are there, so we totally loved it.
It is quite noisy on the street, but it seems to be a part of life in Paris.
Also i would say it is perfect for young couple.

Thank you Sam and Arnaud for your hospitality!
