Cristina and Matteo were great hosts. Their AirBnB is very well organised, and they provide excellent instructions for getting there, getting in and getting around the neighbourhood. The studio is tiny, but very well designed to make the most of space. (It might be difficult, though, for visitors much taller than 6ft2in.) It's also a terrific neighbourhood, with intrinsic interest, and in close proximity to many features of central Paris: close to the river, where you get the best view of the apse of Notre Dame.
