Justin's place is perfect for me and my friends. Very modern, clean and the decors are so chic. Location-wise, can't find a more centralized place than this, very walkable...right next to Pompidou center, 5min walk to Les Halles center station, 3min to Chatelet metro station. Loads of things to do around. We also walked to the shopping area in Le Marais, it took us 15min max. We didn't get to meet Justin, but Daniel welcomed us and gave us a tour of the place, and provided us a PDF guide map for the restaurant recommendations. We are two girls both about 1.65m tall, might be hard to move around upstairs if you are tall. Definitely recommend!
