Excellent stay on Île Saint-Louis!
Pierre's loft offers a tremendous location and excellent accommodations. My family of 5 found it to be very spacious and comfortable. We enjoyed making several dinners in the well equipped kitchen. The market and boulangerie were just minute walk away, as was the original Berthillon (the best ice cream in Paris). My wife and I really enjoyed the seconds walk to the banks of the Seine where we enjoyed our morning coffees and our evening cocktails.
Pierre welcomed us in and made us feel right at home, he left great resources for navigating our way around Paris. Pierre's loft really is central to all things in Paris, we walked to many sites but also used the Metro and RER that were a short walk away.
