Some friends that knows Paris suggested me to take a flat near Canal Saint-Martin. It was perfect for me and my girlfriend, nice area full of bars but quiet during the night. The flat is small but really well organized, really good wifi and suitable to be the base for a good trip. We walked all over the most popular sites in Paris using just sometimes the public transportation, in 20/30 minutes we could arrive everywhere walking. Clément is a great host, he also did a cake for us and was really good.
