If you have the chance to book this flat you should do it. It is, quite simply, the most amazing location you will find. Please imagine the softly pealing bells of Notre Dame waking you up in the morning... Yes, the flat is small - Helene informed us that it is a converted maid's quarters - but, honestly, if you're doing much more than sleeping there you're doing Paris wrong. ;) We fit three in the flat with one bag each with no discomfort. The host family could NOT be more charming and lovely. They greeted us with tea and lunch as the flat wasn't quite ready for our arrival. We had delightful conversation and I helped wrangle their cat for a trip to the vet. On our departure, another cup of tea and a warm fare-thee-well. Truly, this is the best version of Airbnb.
