This apartment is perfectly situated in the 3rd. Arr in between the historic Marais neighborhood and the Canal St. Martin. The accommodations were also thoughtful and stocked with anything you may need. The apartment is small but laid out in a way that feels spacious. I stayed here with a friend of mine and it did not feel like we were living on top of each other - perfect for a similarly situated traveler.
There were complications with communication between us and Marie Claude's helper, Therese, however, leading to a stressful arrival. She was not expecting us/near the apartment when we arrived and did not speak very much English so figuring out when we were getting in to the place was difficult and led to a few hour delay. If you clearly communicate your arrival times beforehand it should not be an issue.
Overall highly recommend for the value - you can't beat the location and price.
