We had a great stay at David's place, and it was lovely to have two rooms so our 15-year old could have his own space and talk to his girlfriend on the phone in private. There was a little problem with the neighbours' plumbing, but David was easily reachable and took care of it, despite being abroad. Good location, close to metro and at walking distance from Gare du Nord. If you want absolute quiet during the night, you are probably going to be happier elsewhere. We were fine with it, as the windows keep out most of the noise.
