Carlos is very warm and friendly. He and a friend were waiting for my arrival and showed me everything I needed to know; Carlos even stopped by a couple evenings later to show me how to work the microwave (only confusing because I don't have one). The apartment was very clean and comfortable. It's not large, but in that sense, is typical of Parisian apartments. I never expected in a million years to stay in Montmartre, but Carlos explained that apart from the usual tourist areas, Montmartre has many village-ey areas, and indeed it does. The apartment is on a quiet street with nice neighbors. It has no elevator, but climbing the stairs was a good antidote to all the eating I did.
