We stayed at Mathieu's place for 2 nights and it was great. The apartment was very clean and spacious for two people. The area is very safe with multiple security doors, was not too noisy at night and is very central to the whole Marais area. Mathieu was a great host, and although we didn't meet him in person he was very nice on the messages, and provided clear and easy instructions for check in and check out. We will stay here again if we come back to Paris. Thank you!
