Nick’s place is wonderful. Perfect location on a street in Marais that is full of shops and restaurant. we always felt completely safe even when coming back late at night. We had 2 adults stay in bedroom and 2 sons (17 and 19) stay on futon. They said it was comfortable and they didn’t feel cramped. There was outside noise that we could hear late at night, but that was easily solved by closing windows. When (not if) I come back to Paris, I would definitely see if Nick’s place is available.
