We just had a lovely stay in Martins apartment. It was clean and comfortable and we had everything we needed! Martin was so welcoming and friendly he was the perfect host. He answered all my messages very quickly and even brought us treats of croissants and wine and cheese which we enjoyed immensely!
The apartment is in a great position only two or three stops on the tube from Gard du Nord and a short walk from the tube station. There is also a bus stop really close by and if you are feeling brave the steps that lead to the Sacre Coeur and only a short distance away.
