I stayed in Lionel's apartment for about 4 weeks with my 2 year old. It was perfect. It's well-equipped and spacious enough. The apartment and the building are very secure, which was of most importance since I was mostly alone with my son. And it's in a building with an elevator, which was also important to me because I had a stroller for my son. It's well located near several delicious bakeries, and awesome shops, grocery stores and restaurants. It's also walking distance from the Sacre Cœur Basilica and the Dali museum, and other awesome parts of Montmartre. All the rest of the Paris must-sees are only a short train or bus ride away. I would love to stay here again when I come back to Paris. Lionel is very responsive and a nice guy. I highly recommend.
