I've rented three different apartments around the canal. Matthieu's was both the cheapest and the most comfortable. One of the other apartments was twice as expensive and half as comfortable. The apartment is pleasant, with plenty of light and a great view. I'll certainly try to stay there again the next time I'm in Paris. I never met Matthieu, but he was always available and accommodating. There was even a map and a bottle of wine on the table when I arrived.
