We had a very nice stay in Yves' flat. It was well-located very near the Canal Saint-Martin, and there were many shops and restaurants nearby. Yves was away when we stayed, but his friend Jeanne welcomed us warmly when we arrived. The flat worked well for us as a family of three and would suit a couple as well. The second bed is a mattress atop the couch; Yves let us know about this right as we made the booking, and it worked fine for us. There was some road noise in the bedroom in the evenings, but that's to be expected since the flat is in central Paris. With the window closed, we could barely hear a thing and slept well.
