We picked Mathieu's place to experience the life on Ile-st-Louis and we didn't disappoint. Seine is beautiful, especially in the morning when we still had jet lag. There are numerous restaurants and bakeries nearby to enjoy. Latin Quarter is vibrant at night.
Mathieu was a great host. He was fast to respond and provided so many tips for our trip. He had an enjoyable note in the apartment that I read thoroughly :).
The apartment was spacious for our family of four. As expected, it is old. I think that my allergy was a little more serious when staying in. But the location was worthy.
