Mathias is a great host. He came to pick me up at the train station. He was always readily reachable and available. He even offered to help me beyond my stay in Paris which is very kind of him. The flat is luminous and the size is very cool for the price. The neighborhood is very hip and you will find everything from bars, restaurants, supermarkets, clothing boutiques and metro stations in close proximity. The street in which the flat is located can get very lively at nights on the weekend, to say the least... so you might have difficulties going to sleep early just like me. But overall you will manage just fine. It's definitely worth the money. I can recommend Mathias and the flat.
