We recently stayed in Christophe's studio. It was a wonderful experience, the location is the best part! It is located in the Montrogueil area, close to many restaurants, boulangeries, and patisseries. The room was a good size for 2 people, had a real bed which was very comfortable! Bathroom and studio was very clean! Les Halles metro station was close, which is convenient to the airport! Loved that there were so many markets close by! Definitely recommend staying here if you want a place in the center of Paris! Christophe was also very welcoming and easy to reach with questions!!
