Everything from booking to checking out of Bertrand's apartment was great. He was quick to reply to any and all inquiries I had before arriving. Bertrand was present for check in and showed us around the apartment.
It's wonderfully situated (a maximum 5 minute walk to a metro station - there are two really close by) and really quiet which is nice and helps to get a restful night's sleep.
The apartment is fully equipped - it has everything you would need.
I would definitely stay at Bertrand's place when I visit Paris again!
