I enjoyed staying at Jean-Marc's little studio. It was right on the border of the 18th and 9th arrondissements and around the corner from the Pigalle metro station, which also means it is close by sex toy shops and the Moulin Rouge but that didn't bother me. I felt safe and I was a lone female traveler. The building is very secure. The flat is on the 6th floor and it's a walk up but that also didn't bother me because I didn't have much luggage, am in great shape and live in a 5th floor walk up in NYC so I'm used to it. It is a small studio but for me it was fine, and the shower is incredible! It's quiet, as it faces the courtyard. There's a Coffee press, microwave in the apartment. Lots of bars, cafes, restaurants around. Close to Montemartre, Sacre Couer, easy to get around the city. Jean-Marc was very quick to respond to my messages and let me check in early, as my bus arrived quite early in the morning. He was very accommodating and a nice man. I recommend Jean-Marc's place!
